Vegetation in Nanjing Letu South Subtropical Rainforest Nature Reserve
The trees in the area have become Feng Shui forests since the second year of Hongwu in the Ming Dynasty (1369), which is more than 600 years ago. According to surveys, there are more than a thousand species of plants in the reserve. The families with a larger number of species include Rubiaceae, Leguminosae, Euphorbiaceae, Lauraceae, Rosaceae and Euphorbiaceae, among which Rubiaceae, Lauraceae, Euphorbiaceae and Euphorbiaceae are all tropical families. The rainforest community structure is relatively complex.
More than 1,100 species of plants and more than 80 species of birds grow in the area. The vegetation in the forest is complete, the ancient trees are towering, and there are more than 10 rare plants. Among them, the most valuable species, Acanthus striata, is listed as a first-level protected plant by the country and is praised by scientists as a paradise for plant living fossils. The rainforest was designated as a "precious and rare subtropical rainforest" by the World Forestry Conference. The subtropical primeval rainforest of Paradise is shrouded in clouds and mists all year round, with a mild climate, abundant rainfall, unique landscape, and rich resources. It is a natural species gene bank. There are 184 kinds of vines in the area alone, and more than 300 kinds of precious medicinal materials such as Bagantian, Aesculus aesculata, Ganoderma lucidum, and Bamboo fungus. "Netted leather, Guanyinzuo, Jianlan and red-leafed vines - Dense flower vine (known as the first vine in China) make Paradise rainwood even more glorious. Paradise subtropical primeval rainforest is also a refuge for rare and endangered animals and plants . In the area, there are national first-level protected plants Erythora sinensis, second-level protected plant sightseeing trees, third-level protected plants Phoebe, as well as 14 species of rare mammals such as clouded leopards and antelopes, and 94 species of common insects are active in the forest. < /p>
The rainforest community structure is relatively complex, and the tree layer can be divided into three layers: the first layer is 22 to 28 meters high, and is mainly composed of Castanopsis leucophylla, Phoebe macrophylla, etc. Although there are not many trees, they grow well and have tall trunks. The diameter at breast height is between 70 and 86 centimeters, all with obvious plate-like roots; the second layer is 16 to 22 meters high, and the main tree species include Phoebe macrophylla, Cinnamomum cylindrica, Rubia versicolor, S. striata, Hainan Du Ying, Huang Qi, etc.; The third layer mainly contains Schefflera, bright-leaf birch trees, various madder trees, white-backed new wood ginger, and hairy May tea. There are many tree species in the shrub layer. There are two types of shrubs. Layer: The first layer is dominated by Roman umbrella trees and nine-jointed trees, with a height of about 2 to 3 meters; the second layer is less than 1 meter high, and its main components include various kinds of purple golden cow, Du stem mountain, cinnabar root, Bailiang gold and Young trees. The herbaceous layer is relatively sparse, mainly including single-leaf crescent fern, light bamboo leaf, Huashan ginger, etc.; in addition, there are also scattered vines and vines with a height of more than 2.5 meters. The variety of vine vegetation in the forest is very wide. There are 54 species of trees, including creeping shrubs, among which the large woody vines include the dense flowering vines, the flower bark rattans, etc.
The board roots of large trees in the community, the large multi-woody vines, and the small tubes. The stem flowers of the tree and Shui Dongge, the strangulation of Ficus, the dripping leaf tips of Ginger and Cypress, as well as the occurrence of vines and cypresses all reflect the characteristics of the rainforest. Therefore, this reserve is studying the characteristics and evolution of the rainforest ecology. It has important scientific value. Animal resources include pangolins, lynxes, cobras, pythons, etc.
A virgin rainforest covering an area of 1,900 hectares has been recently discovered in Huboliao, Shancheng Town, Nanjing County. For nature reserves
