Lushan Plant Internship Report Internship Time: August 1st, XX to August 8th, XX Internship Content: Investigate the main vegetation types, composition, structure dynamics and distribution patterns of Lushan Mountain.

Internship route: August 2nd afternoon: Lushan Mountain Lingshan Street - Da Yue Shan Simple Road - Botanical Garden - including the mouth. Know plants along the way. On the morning of August 3: Lushan site - 1000 meters from Huilong Road. Afternoon: Huanglong Temple, Sambo Tree Easy Road. Comprehensive internship of soil plants. August 8th: Take a bus down the mountain and observe the evergreen broad-leaved forest by Xiufeng.

First, the plant profile:

Lushan is rich in plant resources. The forest coverage rate is 76.6%. There are nearly 3,000 species of higher plants, and in the beautiful mountains of Zhongling, there is also the “Pearl of the Mountain”, the “Pearl of the Mountain”, which is the epitome of the Lushan Mountain plant landscape.

1. On the afternoon of August 2: Lushan Mountain Lingshan Street - Da Yue Shan Simple Road - Botanical Garden, knowing plants along the way.

Among them, the names and names of the 10 plants in Luling Street, Lushan:

1, Huangshan pine: pine branch, straight strip type.

2, cypress: Baike.

Second, the type of Laoshan community:

Lushan is located in the natural vegetation. Because it is located in the mid-subtropical zone, it is more than 1,400 meters above sea level. It belongs to the eastern monsoon region of China's subtropical zone. It is about 700 kilometers away from the sea. In the distribution of vegetation, its horizontal zone is evergreen broad-leaved forest, with altitude. Increasing, the vertical differentiation of surface water and heat conditions profoundly restricts the vertical distribution of vegetation, resulting in a variety of plant community types. From the big aspect, it is divided into two parts: coniferous forest and broad-leaved forest.

,Coniferous forest:

For coniferous forests, the sample we extracted has two points, one

1. Huangshan pine community:

It is distributed in the Guling Mountains and belongs to a community of deciduous broad-leaved forests. Huangshan pine, also known as Taiwan pine, is a negative tree species that is resistant to low temperatures and can grow in poor soil. Generally distributed at altitudes of 800 or 850 meters above sea level to the top of the mountain, the highest vegetation type above 1250 meters above sea level. The vast majority of what we see is artificially replanted. It belongs to the pine family, gymnosperm. There is a clear difference between Huangshan pine and Pinus massoniana in Guangdong. The pine branches of the Huangshan pine grow straight, the main stem and the branches are at right angles, while the masson pines form an acute angle. The leaves of Pinus massoniana are two out, long and thin. The leaves of Huangshan pine are also two, but shorter and thicker.

1. Forest record table: Jianqun species: Huangshan pine: There are 8 trees in 20 years old, 4 in 50 years, and 3 in 10 years. The average height is 14 meters, the breast diameter is 50 centimeters, and the branches are 10 meters high. The crown is 3 meters in width and the life type is fruit. Strong life.

2, grass and wood sample: 1 m × 1 m. The first layer is wild chrysanthemum. The dominant species are wild grass; moss grass:; scale hair fern:. The extra-layer plants include: chicken vine, moss, lichens, wild grapes, and glutinous hooks. The group is composed of: Huangshan pine, many seedlings, strong living, relatively stable, and the underlying plants cannot replace it.
