College student social survey report

Introduction <BR> People and the environment are inextricably linked. Regardless of the past, present and future, human beings are constantly transforming the environment to create an environmental space that is not only used but also beautiful. What the city means is not only the accumulation of artificial structures such as buildings, streets, shops, but also the social, cultural, economic, political and urban residents' diverse life accompanied by many functional facilities and hard landscapes. From the external visual image, the city is composed of its plane structure, skyline outline, various buildings, market facilities, regional landmarks, open spaces, planted gardens and shuttle vehicles. However, these are urban people. The form of matter formed under the choice and chosen behavior implies profound natural laws, social psychology, human emotions and historical vicissitudes.
In the 20th century, the famous urban scholar and architect scholar Lewis Mumford pointed out in his representative work "The History of Urban Development" : "If the life realized by the city is not a kind of praise for itself, then it will pay for the development of the city. All the sacrifices will be without any cost. No matter the power of expansion or the limited material wealth, it will not be able to compensate for the beauty, joy and affection that is lost in one day." "When we walked in the city, we found this." The phenomenon is unpredictable, and the surrounding buildings seem to be able to speak and act like the inhabitants; and through the material structure of the city, past events, decisions made long ago, and long-established values Wait, they all continue to survive and have an impact."

In order to fully recognize the urban environment and the role of people in the process of constructing the urban environment , as a learner of urban ecology, we conducted an internship in the northwest suburb of Beijing on April 5, 2003.
I. Internship Overview We departed from the second floor of Beida Yifu at 8:00 in the morning. After passing through Guanghua Building, Library, Yannan Garden, Li Dazhao bronze statue and Cai Yuanpei bronze statue, we arrived at the south bank of Wuming Lake and saw the overturned stone fish. Through the Weixiu Garden, Chengze Garden, Haidian Park, Liulangzhuang, Beijing Urban Green Belt, arrive at the South Gate of the Yihe Garden, watch the Jingmi diversion channel outside the gate, and then enter the Summer Palace from the South Gate of the Summer Palace to the south bank of Kunming Lake. End the internship along the west bank to Wanshou Mountain and Donggong Gate. Along the way, natural and human landscapes such as greening and construction were surveyed, and certain information was obtained. Some thoughts and conclusions were also drawn. 〖The first ┆文文网 tidy up the article, the copyright belongs to the original author and the original source. 〗

Second, the content and analysis of the internship
1. About a controversial road into the East Gate of Peking University, you can see a wide and straight road. As one of the few broad and straight roads that Peking University has, it is a controversial road. The roadside neatly and well-maintained lawn announces the modernization and internationalization of the new Peking University. This road is surrounded by the relatively modern buildings of Peking University - Science Building No. 1, Building No. 2, Yifu First Floor, Yifu Second Floor, Yifu Court, Science Teaching Building, etc. At the end of the road is an antique-style building with a traditional charm.
Many people believe that the wide and straight road surface is not in harmony with the antique roof of the surrounding buildings. In addition to the neat artificial turf, the two sides of the road are small trees that have been planted neatly, and the end of the road is a tall, shady tree that has been growing for many years. The uncoordinated feeling is more intense.
This probably involves the so-called "visual adaptability." In many cases, we rarely consider a specific environment, but simply apply a kind of model that looks good and advanced, and ignores the special requirements of a specific environment for artificial facilities such as buildings.
Perhaps this is also a problem in planning. Just as the new buildings and old buildings that are everywhere in the Peking University campus, they may not be the perfect choice.
2. The paradise on campus - Yannan Garden Yannan Garden is one of the smaller gardens of Peking University's Yanyuan Garden. There are only a dozen elegant and elegant two-storey small buildings and a small courtyard in the garden. Here is Professor Peking University. A residential area. It is often said that "the famous professors of Peking University do not necessarily live in Yannan Garden, but Yannan Park is a famous professor." In the 1950s, Yan Nanyuan lived with Ma Yinchu, Tang Yongqi, Zhou Peiyuan, Feng Youlan, Zhu Guangqian, Chen Yusun, Hou Renzhi, and Mr. Lin Gengzhu, and later moved in to Wang Li and Wei Jiangong. Ms. Bing Xin also lived here when she was teaching Yanjing University. This is enough to reflect the profound content and cultural accumulation of its connotation.
The independent residential model in Yannan Garden is the ideal environment for academic research by old professors. As an old professor pointed out in an interview, although he was a little old, he would not think of changing the old-fashioned pattern of the house. One reason is that although many books were donated to the library, the collection of books at home also led to Inconvenience of renovation. However, the more crucial point is that the pattern of the old house is an environment that can make people feel at ease to study and study. Years of accumulation have made this little garden full of scholarly spirit...
So, apart from the scholarly fragrance, what does it mean for people who have lived here for a long time?
The interviews were mainly conducted by the elderly over the age of 60, and they lived here for more than 35 years. They generally believe that Yannan Park has a good living environment. First of all, it is located on a platform, and the terrain is higher than the surrounding area. This is a good geographical environment. In the meantime, the plants of different colors provide a coordinated ecological environment for the garden. As a distinctive residential garden, Yannan Park attracts visitors from all walks of life. The teachers and students of the School of Architecture of Tsinghua University have also written here to study the architectural features.
However, Yannan Park also has its shortcomings. The interviewees generally pointed out the following:
One is that the people who came to visit the sightseeing area broke the original tranquility and cleanliness. The passing cars drove the dust and made noise, which caused a great degree of damage to the environment inside the park.
The second is the problem of public toilets. The land occupied by public toilets is the playground of children in the past. Due to neglect of management, the construction of public toilets not only eliminates the children's play, but also has a great impact on the environment. In fact, in Yannan Park, each individual house has independent sanitation facilities. The establishment of public toilets is only for the convenience of small business hawkers outside the park. As one of the few outdoor public toilets that are rare in Peking University campus, its establishment naturally has its own reasons. However, it is located in Yannan Garden, which has rich cultural heritage and profound connotation. It is located in Yannan Park where old professors study and study. Perhaps it is not Very reasonable.
The third is the contradiction between office and residence. As one interviewee pointed out, some of the houses in Yannan Park have been assigned to certain administrative agencies by the school. The office of the administrative agency has further broken the tranquility of the garden and cannot but cause deep thought.
The charm of Yannan Garden represents a part of the charm of Peking University, and it is the style of studying and the temperament of Yiran. Its integrity is an inseparable part of Peking University. Perhaps, its tranquility should not be broken and sneaked...
3, the change of the apple orchard - Jingyuan lawn famous Jingyuan lawn used to be an apple orchard, as a lawn, it replaced the status of the past East Lawn. Once the East Lawn was in the position of the new library, it used to be a romantic lawn that students loved. One North University student wrote: "The East Lawn is the land on the east side of the Peking University Library. It used to be the stage where Gao Xiaosong’s gang took the broken guitar to the big girl of Peking University’s little girl. We have a good place for Peking University to study and relax. Many Peking University couples meet, meet, and fall in love with the Eastern Lawn. Their feelings for this grassland are deeper.... Li Ka-shing said: This land is empty and unfortunate, I give You have to pay for the money, and then repair the library. After one year, there is no one more newspaper or a book here. A building that is more solemn than the Supreme People’s Court has drowned a lot of stories that should have happened."
After the students strongly requested, the original apple orchard was changed to a lawn. The romance of the lawn has recovered, but the rare orchard on the campus has been lost forever. How much is always a pity.
Compatible, maybe really hard. In recent years, in order to accept more and more scholars, Peking University has to connect with the international community. Many original natural and artificial unique scenery can only give way to new buildings, which has caused the feelings of countless Laobei adults. And development always has to be, the key is how to develop, how to use land in a suitable place, and leave our pride in other places. If one day, the Unnamed Lake begins to shrink, or a new building is built around the Unnamed Lake, that is our true sorrow.
"One tower lake map" is not the whole of Peking University. The spirit of Peking University is very wide. The pride of Peking University lies in the culture it creates, the harmonious unity of science and nature...
4, unique ingenuity - the path to the unnamed Lake Trail North University campus can be said to be full of ancient rhyme, like traditional Chinese gardens, in the beautiful romance gives people a heavy sense of thought and history. "The life of Peking University is closer to the traditional literati doctor." A Tsinghua student who always likes to stay in the unnamed lake said. This kind of literary person is arrogant, and the path leading from the strip to the unnamed lake can also be reflected. Its shade and tranquility constitute the unique scenery of Peking University.
There are various plants growing along the quiet path. Striking is the stone under the cedar, its unique use makes people feel refreshed. The waxy substance in the lower part of the pine needle is an acidic substance. When it falls into the soil, the soil is affected by acidification, and the soil quality deteriorates, so that dust will fly when it is windy. The stone can prevent dust from rising, thus ensuring the freshness and cleanliness of the road and air here.
The large eaves of the traditional buildings along the road provide a good living environment for birds such as sparrows, and the sound of birds is endless. Here, the true integration of man and nature is a rare sight.

Xinhuanet reported on October 6, 2002:
"Into the campus of Peking University, on the branches, on the grass, next to the teaching building, in front of the library, on the lakeside, at the top of the Boya Tower... everywhere you can see groups of magpies and other kinds of birds, one school "The scene."
Zhang Liming, deputy director of the Propaganda Department of the Peking University Party Committee, who graduated from the Chinese Department of Peking University 19 years ago, said in an interview with Xinhua News Agency that he saw magpies on campus when he was in college, but there are not many current numbers. Thousands. Now, not only can you see magpies on campus, but you can also see squirrels, hedgehogs and other wild animals. The white swan has also been flying on the lake. During the speech, the reporter saw magpies from the window of his office from time to time. Fly over.
“Now, Peking University campus has become a paradise for all kinds of birds and animals. The campus is full of dignified green cypress, vigorous and rustic pine, gorgeous white pine, golden and golden ginkgo maple and other evergreen trees and spring and autumn. According to the survey of Peking University's gardening department, there are 416 ancient trees in the school, of which 30 are in more than 300 years and 386 in more than 100 years.
Zhang Liming said: "A good ecological environment has become an important part of Peking University's campus culture. "Every holiday, thousands of tourists from all over the city feel the cultural atmosphere of the Peking University campus."

Yes, in terms of ecological construction, we are indeed doing very hard. Just as we were at the West Gate, we saw a magpie that had no fear of people. Sincere joy, rises...

5, the lake island of the unnamed lake and the fisherman's tower of the stone fish, let people forget to return. The unnamed lake has outstanding scenery and has become a symbol of the scenery of Peking University. The willows around the lake are graceful, the branches are drooping, and the water is gently patted. The reflection of Boya Tower appears in the water. There is a stone shovel lying across the lake, dotted with a small island in the lake. The secluded Lake Island is a pearl on the unnamed lake. The stonefish is a unique landscape in the lake.
From the teacher, I learned the story behind it. The island was originally an excellent environment for the vigorous growth of plants such as reeds. It is a small environment with extremely harmonious ecology and forms a unique landscape together with the stonefish. However, during the centennial celebration, the school set up a description card on the island in order to better introduce and explain, which attracted a large number of tourists to the island. The influence of the people caused the growth of the reed to be greatly affected until the reed completely The island disappeared.
Fortunately, the school has realized this, and the explanation card seen today has been transferred from the island to the lake. A self-healing ecosystem should be able to return to its original state after long-term development conditions. In the near future, we can re-own a good ecological island, but not all mistakes can be remedied. Sometimes, a not-so-wise decision can cause great regret. The long-term nature of planning can be seen. I hope that the story of the island will bring us some inspiration.
6. Yanxiu Park and Changchun Garden have a long history of Yanyuan, which is our pride.

“The Peking University Yanyuan Campus has become a famous scenic spot in the suburbs of Beijing in the Jin Dynasty. In the Ming Dynasty, the large-scale construction of gardens became the “grant garden” of the feudal emperors in the Qing Dynasty. During the Republic of China, it became the campus of Yanjing University. The site of the campus includes eight ancient garden sites, namely “Spoon Garden”, “Shuchun Garden”, “Minghe Garden”, “Mirror Spring Garden”, “Lang Run Garden”, “Yu Xiu Yuan” and “Cheng Ze Yuan”. And the "Beizi Garden", etc. It is adjacent to Yuanmingyuan in terms of location, and it has similarities with the gardens in the Wanchun Garden of Yuanmingyuan in terms of content and gardening style. Unlike the magnificent royal gardens, it is also different from the private gardens of the mountains. The garden is unique and unique. After the vicissitudes of life, many ancient gardens or the fire of the imperialist powers that were paid together with the Yuanmingyuan, or were sold and sold by warlords, many have been razed to the ground.... Shuchunyuan, Langrun Garden, Minghe Garden Chengze Garden is a survivor, and the water surface of the hills is still intact. This is a long-standing witness of the campus and a valuable cultural relic.
"In 1920, Beijing Tongzhou Concord University, Peking Union Women's University and Beijing Huiwen University merged and completed Yanjing University. The principal, Situ Leiden, bought the Shuchun Garden and the southern garden of the spoon from the warlord Chen Shuzhen for 60,000 yuan. Architect HYMrphg was responsible for campus planning and design, and started construction in 1921. It was basically completed in 1929. The campus originally used 40 hectares of land and 800 students. From 1928 to 1931, it was awarded Langrun Park, Minghe Garden, Jingchun Garden and Weixiu. The Garden and Chengze Garden are the welfare quarters for the faculty dormitory. In the same period, the Beizi Garden was purchased as the internship site of the Yanda Agricultural Science Department. The architectural function and environment of the Peking University’s unnamed Huyan Garden are unified, and the architectural art is in harmony with the environment. The individual buildings are in harmony with the ancient garden style, the vertical and horizontal architectural axis layout and the garden environment are mutually infiltrated, and the application group motifs form a harmonious rhythm. The spatial sequence of the building and the landscape, the road and the trees are combined to make people A variety of beautiful feelings."

Looking back, let us have more desire to understand. What are the gardens that are today as a faculty residential area?
Entering Weixiuyuan, the charm of the hometown is faintly discernible. However, the feeling of "the spatial sequence of architecture and mountains, roads and trees that make people feel a variety of beautiful feelings" is gone. The building and the bungalow on the same plane indicate their existence, and the asphalt road and the dirt road show their functions on the same lake. Because there are a few low-priced hotels that are very simple and simple, the people who come here are all different, destroying the quiet and comfortable environment. Due to excessive openness and poor management, Wei Xiuyuan’s today is very disappointing. The rubbish everywhere, the rudimentary small restaurants and the equally rudimentary small hotels make people lose interest...

So what is the reaction of the residents who have lived here for a long time?
Residents near the lake are mostly “dirty and messy”—the garbage can be seen everywhere, and the emissions from the bungalows on the lakeside are seriously polluting the environment. The lake is mainly from the Wanquan River. It does not release water in the winter. In the summer, it is stinky due to pollution, and the mosquitoes are in groups.

As for the residents who are a little farther away from the lake, they think that life is not satisfactory except for poor management. Moreover, the location is convenient, and it is close to the Summer Palace, Xiangshan and Peking University headquarters, and it is more suitable for living. An old man who looks like a scholar said, "There is very little environment in the university." An old man who seems to have eight or ninety years old living with his son said: "The environment is OK, it is better every day."
One problem that residents generally reflect is that there is no large supermarket nearby and shopping is inconvenient.

In Changchun Garden, we encountered the same problem. I think the main reason for this is poor management. An old aunt who used to work in the dining hall of Peking University repeatedly asked us to prove that it was a student of Peking University. Only after telling us a lot of questions about it, she was very moved by the maintenance of Peking University’s reputation. However, as a faculty dormitory area of ​​Peking University, it is impossible to improve the level of management, so that it has become a residence for migrant workers in Beijing. This cannot be ignored. In the long run, the maintenance of the residents is impossible to maintain the reputation of the garden and the reputation of Peking University.

7. Wanquan Cultural Park <BR> Park is a centralized space where public art and green ecology are integrated. After the middle of the 20th century, the industrialization and urbanization of European and American countries have developed rapidly. The urban space has expanded and spread with the development of population and economy. The industrial and mining production and processing forms, especially in the post-industrial era, urban housing, energy, and transportation. The communication and the pressure of the overall ecological environment have become a vicious development trend, which has caused the natural ecology, the diversity of flora and fauna and the richness and integrity of the heritage of human history and culture. This scenario is particularly common in poor and developing countries. The parks set up in many central and suburban areas of large cities are far from enough to significantly improve and optimize the urban environment. Most of them only play a high concentration, high speed, high return and high consumption for urban society. The suppression of the mind and the damage of the ecological environment do some adjustment, soothing, or temporary short-term digestion and escape.
Despite this, the park still more or less represents the praying and symbolic return to the already-defunct natural scenery or the rural landscape of the farming era. In many urban streets, plazas, and community centers that have gradually lost the function of public communication and leisure places, and lack of beautiful green ecological environment, good parks have more urban gardens and “city lungs”. The value of the value.
Wanquan Cultural Park was established under such a background. It used to be a morning market in the past. Later, it was cleaned up and reorganized to form a park, which became a good place for nearby residents to exercise and relax. It is a semi-open urban street park, which includes landscapes such as rockeries and lawns, as well as public recreation facilities such as children's play areas, elderly fitness areas, dance floors, and roller skating. What is commendable is that the ground here is paved with soft materials, which are both beautiful and protective. We arrived here around 10:00 am, many children are playing, many middle-aged and elderly people are exercising, and many people are flying kites here, which is a lively scene.
We interviewed visitors randomly. In the interview, most visitors said that they lived nearby, often come here, and sometimes even came here for the sake of distraction. Most of them said that "the environment is ok, the equipment is good, and it is much stronger than before." Parents with children say they are safe and secure about their children. Most of the dissatisfaction is concentrated on the hygiene of public toilets. It is said that the public toilets here are unmanaged, and often the sewage flows across the river, making the clean and beautiful environment a great sight. In addition, the lack of trees, this led to people in the summer, because there is no place to take a cold, but had to take a walk in the morning or evening, lost the use value during the day, can not but say that it is a lack.
Wanquan Cultural Park is a successful plan in general. If it can strengthen the management of the park, it will be a masterpiece of ecological construction in the western suburbs of Beijing.
8, Wanquan River walked to the Wanquan River, stinking. There is a white foam on the river, and the river is already black. The reason is that a large amount of sewage is discharged, and the amount of emissions has exceeded its self-purification capacity. The artificialization of the river channel makes it separate from the natural life process, and its self-purification ability is greatly reduced.
With deep regrets about the pollution of Wanquan River, I checked some relevant information online.
The "Beijing Morning Post" on February 22, 2000 published a report entitled "People reflect the stinking of the lake in the campus of Peking University." The report pointed out that since the beginning of winter, the lake in the campus of Peking University has been slow to freeze, white foam floating on the lake, and an unpleasant smell of rotten eggs. When the reporter investigated, it was found that the fish in the lake clung to the ice, attracting everyone to cut ice and fish. According to experienced people, fish only float in the water to absorb oxygen in the absence of oxygen, indicating that the lake is lack of oxygen due to pollution. At this time, Wanquan River did not freeze. According to the staff of the Wanquanhe Management Station of the Haidian District River Management Office, Wanquan River is a river used for drainage in Haidian District. The lakes in Peking University and Tsinghua Park rely on this river to circulate the lake. In the past, the rivers were frozen. Icing is due to oily pollutants in the river. The staff also told reporters in particular that fish caught from this water may be contaminated and the residents must not eat.
The Beijing Morning Post on February 25, 2000 published a report entitled "Difficulties in Solving Beijing Wanquan River." In an interview, Director Wang of Haidian District River Road pointed out that the Wanquan River, which has been seriously polluted, cannot find out where the source of sewage is. The only expedient to solve the stench of Peking University residents is to introduce clean water from the Jingmi diversion canal. The river will be washed out. "But it won't last long. After two or three days, the water is still like this." Why can't the sewage source be detected? It turns out that the Wanquan River began to be rebuilt in 1982. After the renovation, the river water was introduced from the "Jingmi". In the past two years, the municipal construction of Haidian District has been accelerated. Some units and individuals have saved money and saved the troubles. Into the rainwater pipes used to drain rainwater during heavy rains, causing sewage to flow directly into the Wanquan River. These private pipelines cannot be detected because of the funds and manpower restrictions in the bureau, so the pollution source cannot be seen.
What is even more surprising is another report titled "White skin is tender and tender, and the 'Weird Frog' swims in the Wanquan River in Beijing." A surnamed Chen found a "freak frog" in the Wanquan River near Ximen, Tsinghua University in October 2001. It is flesh-colored, without any pattern, and the skin surface is very smooth. The hind legs of the frog are particularly strong, and the red muscles on the legs are clearly visible. The forelimbs are particularly small and can not support the body when squatting. The staff of the Beijing Wildlife Conservation Station said that this may be an albino frog. Albino phenomenon is a variation caused by genetic mutations, which can occur in many wild animals such as mammals, birds, and amphibians. There are many factors that cause whitening, and river pollution is one of them. This fully illustrates the seriousness of water pollution in Wanquan River.

There is no need to say anything more. The water pollution of Wanquan River has reached an extremely serious level, and its pollution has a bad influence on the surrounding water environment. Controlling the source of pollution should be the most fundamental solution, and the EPA claims that the source of pollution cannot be detected. Then, a thorough and firm environmental action is still important. If you do it steadily, it is impossible for the source of pollution not to appear. Administrative management and measures have yet to be further strengthened.
9. The green belt can see a big slogan on the road to Liulangzhuang – “protecting the forest green space and consolidating the greening achievements”. It is established by the Haidian District Municipal Administration Committee. You can also see a group of soldiers carrying tools to plant trees. This reminds us of the ongoing green belt construction activities in Beijing. This kind of construction has given me an interest in the historical changes in the western suburbs of Beijing. I found some information.
About the change of "Haidian" Mr. Tao Shilong wrote in the article "Historical scenery of Jiangnan Water Town in the history of Shanghai Dian - according to Hou Renzhi: Excerpt": "Haidian has a lake. When he came to Beijing in 1948, he passed the Yanjing University and now the Peking University campus. Go to the Summer Palace, turn north to the west, and see the area of ​​Lusongtang; in the early 1950s, it was still in the farmland. The roadside was mostly farmland, the soil was rich in water and water, and the Jingxi rice was out, and more lotus roots were planted. ”
Mr. Hou Renzhi mentioned in the "Qing Qing Ji":
"In the Qing Dynasty, there were densely landscaped gardens in the Haidian area, and there were lakes in the garden. There were many waters outside the garden. The wind planted the wind and the fragrant rice in the fields, just like the Jiangnan water town, with poems as evidence.
Suddenly, I went wild to the rivers and lakes, and went into the drawing along the moon.
A few songs are connected to the liquid, and thousands of lights are scattered. -- Qingren 咏 unnamed lake predecessor scenery Wanquan Shili Shuiyun Township, Lan Ruo leisure looking for Xiaoxiao.
On both sides of the green yang, the light boat is full of rice and wind. -- Qianlong's self-traveling garden from the West Garden of the Spring Garden to the Shenghua Temple, depicting the scenery of the water town near the Bagou. ”
Is this change a progress, or is it a mistake and a retrogression?
Disappearing scenery: Liulangzhuang, Haidian, Liulangzhuang, Jingxi, Donghe Changhe, west of the Summer Palace, after five hundred years of living, there are thousands of families, known as the first village of Jingxi.
Liulangzhuang is the hometown of Jingxi Rice. In the Qing Dynasty, there were 360 ​​acres of rice fields, and the Royals ate a day. There is also the saying of "Six-Thirteen-Circle of South Qibei": When the rice paddy was opened in the same year, the Qing court packaged the project to Nanqi, Beiliu, and 13 provinces. So far, there is still a "prosperous place" in the south of the village. Place name. Emperor Qianlong in the "Wanquan Dyke on the Temple of the Temple of the King", there are also "Wanquan for a long time to stagnate, Jia Shenyin began to dredge, that is, its land to open paddy fields, this spring to add to the opening" note. He also described the scenery of Liulangzhuang in the poem "The weeping willows are hidden in the village, the new seedlings are indifferent to the paddy fields".
Jingxi rice is full of seeds, steamed out of the rice to scent. It is said that Chairman Mao tasted the rice made with Jingxi Rice in the Summer Palace in the early days of liberation. He even said “good food” and proposed to promote Jingxi Rice.
However, Liulangzhuang, which has a history of 500 years, is about to disappear because it is on a green belt. According to the overall plan of Beijing, the pattern of the Beijing area is “distributed group system”, that is, the city consists of the central area and the surrounding ten marginal groups; between the central area and the marginal groups and the marginal groups, Green areas are isolated. The Wanliu area where Liulangzhuang is located is located on the 100-meter green belt next to the Summer Palace. After the implementation of the Wanliu project, the local farmers will go upstairs and return farmland to forests. Liulangzhuang will become a green scenic spot.

Seeing that Liu Yaozhuang, which is disappearing from Jingxi Dao, is in a state of construction, the mood is really complicated.
The establishment of a green belt In order to build a green ecological framework in the capital region, Beijing has made the decision to build three green barriers, namely the first green barrier based on Yanshan and Taihang Mountain greening projects, with 5 rivers and 10 roads greening and farmland. The second barrier, which is the focus of the forest network, is the third green barrier formed by greening the isolated areas.
The greening and isolation area is the nearest green barrier in Beijing's urban area. According to the “Beijing Urban Master Plan”, an urban forest with a green area of ​​125 square kilometers is constructed between the urban central area and the 10 marginal groups and between the various marginal groups. The project has been implemented since 1986. This year, the construction of the isolation belt has completed a green area of ​​35,000 mu, which is the sum of the green areas in the past six years, and formed 10 green plates with an area of ​​about 5,000 mu. After the 10 green plates are connected to each other, they will form an ecological barrier around Beijing, which will play an important role in improving the ecological environment of the capital.

It is true that the construction of green belts is a major measure of Beijing's ecological environment construction, and it is a good thing for the benefit of the country and the people. However, Beijing West Rice represents a culture, a resource and a tradition in Beijing. Jingxi Rice has gradually disappeared with the construction of Beijing. Now its homeland will cease to exist. When it completely disappears from our vision, what are we lost?
Why can't there be a solution to find the best entry point for ecology while examining and carefully treating cultural resources and traditions? Perhaps, Beijing West Rice, should not have disappeared from Beijing; perhaps, Liu Langzhuang, should not have disappeared from the map.
10, Jingmi diversion canal and Beijing water treatment Beijing water environment governance Beijing water environment governance is a major project, but also a project that has been continuously carried out in history. The center of Beijing used to be a lake group in ancient times. From Kunming Lake, it can be navigable to the Forbidden City. There is also a river of rivers and a moat surrounding the Imperial City and the capital. The lakes and waters are connected, making the historical name of Beijing all outside the majestic atmosphere. It is beautiful and elegant. However, since the end of the Qing Dynasty, due to the neglect of the Beijing water system, the river has accumulated pollution and the shipping has been abolished. After the founding of the People's Republic of China, Beijing has carried out three major remediations of the urban water system. Two reservoirs, Guanting and Miyun, were built. The Yongding River diversion canal and the Jingmi diversion canal were excavated, and the water from the two reservoirs was introduced into Beijing, increasing Beijing's The amount of water used in the environment and the water environment have been greatly improved. However, after all, the water system has not been completely cured for more than 40 years. After the 1980s, the economy developed rapidly, the number of migrants increased sharply, rivers and lakes were polluted, and some rivers became stinking ditch. The lake has deep mud, and according to the monitoring of the Beijing Municipal Water Resources Department, the accumulated sludge has reached 2.3 million cubic meters.
The deterioration of the water environment in Beijing has aroused widespread concern from the central and municipal governments and citizens. At the Beijing Municipal People's Congress in early 1998, 225 representatives of the Municipal People's Congress jointly proposed a proposal to govern the pollution of urban rivers and lakes. On September 26, 1998, urban water system management began with the six pearls that governed the heart of Beijing, the “Six Seas”. The goal of Beijing's water system governance is “water clearing, shore green, smooth, and navigable.” This water system governance is the first time in Beijing's history. There is no precedent for large scale and high investment.
Jingmi diversion canal--After Kunyu River, another landscape river channel Jingmi diversion canal technical reconstruction project is a basic construction project to solve Beijing urban water supply, with a total length of 112.7 kilometers, becoming the most important "large artery" in Beijing water supply.
According to official reports, in 1989, the Jingmi diversion canal began to deliver water in the winter. From then on, the water transfer task of the diversion canal was changed from seasonal water supply to perennial uninterrupted water delivery. However, after more than 30 years of overload operation, the Jingmi diversion canal has been aging for a long time, and most of the earth excavation is severely eroded, and the soil is heavily deposited, which affects the water delivery capacity. Channel damage causes great waste of water. According to the statistical analysis from 1990 to 1999, the leakage and evaporation loss rate of the Jingmi diversion canal was 23% on average, and the highest in 1999 reached 32.7%. It is very urgent to carry out technical transformation. After the completion of the technical upgrading project, the channel's water delivery capacity will be enhanced, which will enable the valuable surface water resources to be fully utilized and saved, saving 100 million cubic meters per year. This spring, the greening of the two sides of the Jingmi diversion canal was started. The design scheme is that the grass and trees are clearly layered. The Jingmi diversion canal has become another landscape river after the Kunyu River and the South Moat River.

However, as far as we know, the Jingmi diversion channel was basically naturalized before 1998 and is now fully artificial. In the past, there were tall, shady trees beside the canal, and today there are only neatly sized trees just planted next to the straight river bank. The Jingmi diversion canal has now become a landscape river, and you can see the cruise ships above the river. Visitors who come here often have regrets about the disappearance of natural rivers, but also understand the remediation of the environment. It is said that there was no one in the past, it was very chaotic, and now it is much better.
11. The Summer Palace Summer Palace is the best garden in the Beijing-Tianjin region. I think that the last stop of this internship is here to explore the beauty of ecological construction and to find deficiencies in the United States.
Perhaps for the Summer Palace, there should be a lot of things to say, but I don’t know where to start. Because it is too big and too spectacular, and it contains too much beauty, too rich thoughts and culture. Everyone has too many comments and praises, and I seem to seem redundant. Then talk about some things on the back!
On the west bank of the Summer Palace, a middle-aged couple talked about their views on greening. They believe that the greening of Beijing, including the Summer Palace, should have its own characteristics. It should create new ideas while pursuing nature, and the current greening is very deliberate and uniform.
On the west bank of Kunming Lake, we saw another shocking shot that everyone would not want to see: a long pipe that drained black sewage into the lake... At that moment, we were silent It is. In this similar scene, I used to see it on the beaches of Qingdao. However, as a lake, the self-purification ability is far from the sea. I don't know, under the opportunity of the Olympic Games, vigorously promote the key moments of the ecological construction and environmental protection of the Summer Palace. What does that tube mean? Quick success, after all, is not the way to solve the problem.

Third, thematic analysis and thinking
1. About Greening Peking University Campus Greening In the "Analysis and Suggestions on Greening of Campus Functional Areas", there are some ideas about the greening of Peking University campus.
According to the principle of campus greening, the dormitory area should be fresh air, beautiful and comfortable environment, rich in flowers and trees, suitable for tree-shaped evergreen trees and flowering shrubs, so that the dormitory area has four seasons of spring, summer, autumn and winter.
The teaching area should adopt a neat gardening technique. The trees should be planted, planted or planted with hedges on both sides of the building, and large lawns should be laid in front of the buildings, with beautiful flowering shrubs or planted ground cover plants. Avoid planting flying trees and plants that are susceptible to allergic reactions. There are some problems with plant greening in the teaching area. For example, Sanjiao is adjacent to the Wusi Stadium. There are only small shrubs such as cypresses and small trees such as pebbles in the middle. The lack of noise is prohibited, which makes the normal learning in the teaching building greatly affected. The eucalyptus planted on both sides of the main road around the cultivating school is prone to pests and affects the appearance. In addition, there is a lack of trees around the science building group, which is slightly monotonous.
The administrative district serves as a window for the school to communicate with each other, and the layout of the garden is better. There are many kinds of trees, such as cedar, ginkgo, white pine and other tree-shaped trees. They stand on the bluegrass lawn in the form of isolated trees. They are quiet, solemn and solemn, and meet the requirements of the administrative area. The fly in the ointment is that the flower bed in front of the office building has passed, has withered and turned yellow, no one cares, and is extremely inconsistent with the surrounding landscape, it is unsightly, it is recommended to update in time to ensure that the colors are always fresh.
The recreation area mainly refers to the garden area around the unnamed lake. There are many kinds of plants in this area, which tend to be natural habitats. The trees, shrubs and herbs are naturally layered, and the trees are highly closed. It is a good place for leisure, entertainment and learning.
In short, when we carry out new greening construction, we must pay attention to the comprehensive consideration of the characteristics of the plant itself, the spiritual connotation of the plant and the attraction of the attraction, the construction, the feasibility of implementation, and the cost saving.

The artificial nature and the complete nature can be said to be a problem that has been discussed for a long time, but the conclusion is so difficult.
It’s like a well-formed lawn on the campus, and the weeds that cling to the clumps; just like the stalk of the plantain in Yannan Garden, it’s still strong when it’s stepping on it; just like the February blue, dandelion, no It needs to be watered and flourished; it is like the trampled grass in the quiet garden lawn; just like the bluegrass that just sprouted in the spring; just like the reeds in the unnamed lake island...
What is the function of the lawn? Is it watching? Is it beautiful? Or is it close enough to nature? The artificially maintained lawn always shows a bit of separation and self-extraction away from the dust. The rotating sprinklers make people doubt the power of nature. An automated lawn mower makes people's power almost close. Weird worship. I have been accustomed to the signboard of "the lawn is forbidden" since I was a child, always aligning the entire lawn. Suddenly I remembered the strange look of passers-by when I was having lunch on the lawn on the south bank of Kunming Lake. Vaguely heard the voice of contempt: eating on the lawn, isn't the lawn more dirty? So I thought of myself in the past, seeing others picnic on the lawn, always filled with indignation... However, the current thinking has changed a lot, although there is always some hesitation and anxiety when stepping into the lawn. Yes, if people are always isolated from nature, how can the natural beauty be experienced? Get close to nature while protecting nature...
I saw many examples of this along the way. And sometimes the power of nature and its sophistication are really impressive. On the lawn of Yannan Park, more than a dozen plants coexist in harmony, and the presence of earthworms creates an extremely good growth environment. Where weeds and artificial grasses coexist, weeds always precede grass and green. Natural objects that are separated from life processes in nature are always extremely fragile. In the wilderness of Liulangzhuang, the pioneer plant ash is grown. As an annual plant, it can grow very high in a year and has a great improvement effect on the soil. After 3-6 years, the ash is replaced by other plants, and the two-year-old herbaceous plants, perennial shrubs, and trees are gradually growing. On the Wanshou Mountain in the Summer Palace, there is an ancient soil and water conservation project. The shingles are built on the mountain to strengthen the infiltration of rainwater and slow down the downstream flow of rainwater, so that it can play the role of water retention and soil conservation. Make full use of the natural characteristics to serve the nature. On the Longevity Hill, arborvitae under natural conditions and other plants that grow well under natural conditions are grown, while the gardeners want to clean them all up and have a variety of grasses on the mountain. However, the artificial grass that is not drought-tolerant requires more artificial watering, which provides an unfavorable growth environment for the arborvitae, and ultimately leads to unfavorable ecological results. Trying to artificially change the choice of nature will surely give you a choice against the nature.

2, on the rectification of the urban environment <BR> We have a responsibility, that is, not only carefully consider the meaning of beauty, but also open ourselves to experience the beauty and follow the guidance of the United States. This unique adaptation of humanity can help us develop an ethical relationship with nature.
——LK Austin

In many urban communities and urban-rural areas of China, due to the land use pattern and the increasing pressure of the population, large areas of exposed land have been subjected to long-term erosion and desertification. The original forest vegetation has been easily discarded; water shortage, garbage and wastewater Inadequate processing systems and increased environmental pollution have brought long-term and potential crises to the healthy survival and development of ecological communities. On the other hand, historical and cultural landscapes such as old architectural streets, streams and cultural attractions in the community are easily dismantled, disintegrated or destroyed in the reconstruction and construction of the community. This obviously does not match the concept of “sustainable development”. In Beijing, this situation also exists. During our internship in the western suburbs of Beijing, we saw a lot of such situations.
"In the modernization of the capital city, we must correctly handle the relationship between economic society and the population, resources and environment in accordance with the requirements of people-oriented and sustainable development, improve the level of urban planning, construction and management, and promote the coordination and harmony between people and cities, people and nature. Create a road to urban civilization development with economic prosperity, rich life and beautiful environment..." The report of the Ninth Congress of the Communist Party of China has drawn a beautiful blueprint for the next five years: the per capita green area will be more, the air will More fresh, the people's housing will be more spacious, the roads will become wider and wider, and traffic jams will become less and less... The quality of Beijing's human settlements will become higher and higher.
The municipal government has established an investment of tens of billions of yuan to create the beauty of “Bishui around the capital”. At present, many of the old stink rivers have become a good place for citizens to relax and entertain. Beijing will invest another 5.45 billion yuan to carry out large-scale urban river improvement. In 2005, there will be no stinking rivers in the urban area. The change of Wanquan River should be just around the corner.
The Beijing Municipal Government has also identified 138 key urban environmental remediation tasks, namely, the plan to relocate the Yuanmingyuan Relics Park, the rectification plan around the Central Television Tower, the environmental remediation plan for the surrounding areas of Tsinghua University and Peking University, and the environmental remediation plan for the surrounding area of ​​the Summer Palace. Planning and design of environmental construction projects in key areas such as the construction of urban wall ruins and parks. However, this kind of rectification has not been so smooth.

"Beijing Morning Post" reported on December 01, 2001, "Between the south wall of Weixiu Garden outside the West Gate of Peking University and the north wall of Changchun Garden, there is a small alley of three or four meters wide. This is the area of ​​the Douqiao Bridge. The private bungalow is full of private buildings, and the environment is so dirty. At present, it has become a demolition site. After half a year, a wide and clean garden-like new road will be built. The Qidouqiao area and the Xiyuan in the south. On the playground road, the two small roads are only two or three hundred meters long, but there are dozens of small shops, six or seven hair salons, as well as restaurants and bars. The environment is messy and extremely incongruous with the cultural atmosphere of Peking University. To this end, Beijing The two levels of government and Haidian District jointly worked with the Ministry of Education and Peking University to raise 130 million yuan for rectification and demolition. The area of ​​the Koudouqiao area will be moved to Changchun Park in the south, Weixiu Garden in the north, Qiheyuan Road in the east, and Qidou Bridge in the west. It involves 84 households, 7190.06 square meters of demolition area and 227 demolished population. At present, most people have moved away, and the noisy small street has now become a demolition site. Soon, a 10 meter wide street will be built here. With green beauty The area of ​​the Douqiao Bridge will become the Garden of the Bridge."
It has been more than a year since the reporting period. However, during the internship, the Qidouqiao area seems to be describing the situation. The “wide and clean garden-like new road” seems to be still in the cradle. It cannot be said that it is a deficiency and loophole in the urban environmental remediation work. Only planning to do nothing, the remediation process is very resistant, even in the capital Beijing, it is really a bit chilling.
3. Reflections on urban environmental art From Wanquan Cultural Park, I thought of urban environmental art.
Humans walked out of the caves and nests, built earth and trees, and created a place for their own survival. The industrialization and technological revolution have created a lot of wealth for mankind, and they have paid a painful price for it. A series of problems such as population, resources and environment have become more and more serious. In the face of noisy, crowded and polluted cities, people are eager to return to the embrace of nature, to breathe the fresh air of nature, to enjoy the bathing of the sun, and to create a new living environment that integrates with nature.
Breaking into the high-rise buildings of Yuntian, the cobweb-like highways, the endless stream of vehicles, the splendid city night scenes and the grotesque window of merchandise, have created a picture of modern life in the modern society. Today, instead of living in a natural environment, it is better to say that life is in an all-encompassing artificial world. This artificial world, while relying on the natural world as material support, has moved people away from the natural nature. It inspired people to ponder the question of whether, under the conditions of industrial society, whether a beautiful living environment can be built and the increasingly tense New problems such as land resources, increasingly crowded traffic, and a deteriorating urban environment. How to maintain the city's landscape is a new problem facing urban development. The environmental space of modern artificial cities can only create a better future for human beings if they are artificially designed to express the natural environment and natural in the environment. While creating the modern life of mankind, environmental art also designs the civilization of the future of mankind.
In the urban environment, there are many soft landscapes that are convenient for people to live, play, and traffic, as well as soft landscapes such as plant greening and various water bodies. As functional facilities and tools in urban society, they constitute the physical elements of urban environmental landscape. In addition, many natural landscape resources exist in many urban or suburban environments. If the setting of public art is coordinated with these artificial hard landscapes, soft landscapes and non-artificial natural landscapes, it will make the pure spirit public. The art works together with the surrounding environmental factors constitute a public art landscape with greater spatial extent and psychological effects, so that the overall structure of the urban architectural environment, public facilities environment and natural ecological environment can better serve its service functions. It reflects the aesthetic value and humanity principle of its art and culture.
In the survival and promotion of environmental art, it is inevitable to face the ecological balance and ecological maintenance needs of the human settlement environment and related areas. On June 5, 1972, at the "United Nations Conference on the Human Environment" in Stockholm, Sweden, a declaration aimed at inspiring and knowing the people of the world to maintain and improve the human environment, the Declaration on the Human Environment, was adopted. The declaration emphasizes that “...the settlement and urbanization of people must be planned to avoid adverse effects on the environment”. It reminds us from one side that we should do the following for the planning of the land environment and the promotion of larger public art:
1. Establish a sense of protection of the ecological environment in social culture and economic development activities.
2. Cherish and rational use of land and landscape resources.
3. Reflecting and avoiding the state of behavior in the art planning and creative activities that hinders the extreme social health, happiness and sustainable development of human beings.
4. Clarify the interaction between public culture and art and the ecological environment.
5. Establish principles for coordination and integration between public art promotion and urban environment and landscape planning.
Objectively, public art should play a part in its role in beautifying the environment, promoting popularity, promoting correct ecological concepts, and assisting the green revolution in the transformation and maintenance of the living environment and ecological environment of contemporary cities. In the process of urbanization and industrialization in China, the natural environment and green ecosystem have been destroyed and unbalanced as before. The forest, green space, wetland and surface water resources have disappeared a lot, which has become a threat to the living environment of the city and threaten the health and sustainable development of human society. Serious Problem. Therefore, no matter from the purpose of safeguarding the macroscopic ecological environment of human society, or from the aesthetic effect of public art and its landscape, we must emphasize the close relationship between public art and green ecological construction in urban environment, and promote public art in general. Balance and harmony between the hard landscape and the green ecological elements to achieve the effect of optimizing and “softening” the urban environment.
Urban environmental art, a kind of progress and comfort in the choice.

Fourth, the internship summary <BR> one day of internship, learned a lot of things. For the first time, I used a new look to see the grass and trees around me. Suddenly I found a lot of theoretical knowledge in practice, and I was so happy and even overwhelmed. Indeed, urban ecology is a discipline that requires a lot of nutrition from practice. Only by constantly practicing and constantly exploring and progressing from practice can we truly understand the true meaning of this discipline. And the scope it contains is so vast, and the impact it brings is so profound...
In the internship, I also found many things that I have neglected before, which are pleasant and not so pleasant. From the road from the east gate of the school to the Kunming Lake in the Summer Palace, there are too many memories and reflections. There is still too much waiting for improvement in the urban environment, and there is too much need for further planning and governance. Saving and remediation is another dilemma. How to maintain Beijing's style as a cultural ancient capital, while developing the economy and construction, while raising Beijing's ecological construction to a new height, it is necessary to cause a lot of thinking. What I can do now is to write them down, re-examine them, and make progress in the review. And if my review can lead to even a little progress, I am very satisfied.
