Studies On Plant Diversity And Conservation In Yunmengshan Forest Region

In this dissertation, the author analyzed plant biodiversity in Yunmengshan forest region with field survey on plant species and forest vegetation, the results show that: The vascular plants in Yunmengshan forest region include 548 species (variation) which belong to 319 genera, 98 families, the flora geographical composition are complex, the dominant characteristics of flora are temperate zone plants which account for 55 percent, herbaceous species occupy 75 percent exclusively. Evaluating the threatened hierarchy of plants in Yunmengshan forest region, the results show that the number of critically endangered species is 7, endangered species isll, vulnerable species is 53, lower risk species is79,safty species 376. In this region, the plant vegetation was classified into 22 forms, which belong to 3 groups of vegetable types and 5 vegetable types, the widest distribution is Quercus mongolica community. Calculating the value of forest resources, we can see that the total value of forest resources in Yunmengshan is 836.6766 million RMB, in which the eco-benefit value is 781.4521 million RMB that occupy 93.40 percent and the value of forest area and wood is 5.4368 million RMB that occupy 0.65 percent. Analyzing the distribution of forest resources and protecting forest ecosystem in Yunmengshan forest region, establishment of nature mini-reserve chains and biological corridor are necessary.
