Study On Plant Species Diversity In Wanda Mountain Area

The species live in the region of the Wanda mountains are comparatively rich.The Wanda Mountains preserve protected plants and resource plants that are endangered.It is worth studying on them for their high economic value, scial value and ecology value. Floristic research and analysis for this region are also of great importance for the protection and usage of plant resources.This paper analyzed the species diversity in Wanda Mountains by mainly three aspects. By calculating different kind of species diversity index, reflecting the richness,dominance, evenness,the community information and the community complexity.We display the location of different area of Wanda Mountains and the species diversity of the tree shrub and grass in the form of charts out to reflect changes of species diversity in various regions Wanda by using Matlab. The plants list of the Wanda Mountains is based on the articles and fieldwork investigation results. By combining wild research results and current documents, supplementing plant lists in Wanda Mountains area, we can get Floristic characteristics of Wanda Mountains by conducting fauna analysis and therefore can reflect the diversity of species of Wanda Mountains area. By comparing similarity analysis and plants distribution, we could confirm the relationships between the Wanda Mountains, the Changbai Mountains and the Xiaoxing an Mountains.Wanda mountains area has a total of 94 families, 336 genera, and 687 species of seed plant. There are 687 species of spermatophyte belonging to 94 families and 336 genera. Among which, the gymnosperm has 5 species, 3 genera and 1 family, the angiosperm has 682 species, 333 genera and 93 families. The flora features of the Wanda Mountains are temperate character and the floristic elements are extensively related to other areas.The Xiaoxing an Mountains, the Wanda Mountains and the Changbai Mountains belong to Northeast China region. Referring to the similarity analysis, the similarity factor between the Xiaoxing an Mountains and the Wanda Mmountains is higher than that between the Changbai Mountains and the Wanda Mountains for three levels:families, genus and species. That indicates that the plants of the Wanda Mountains may be more related to the plants of the Xiaoxing an Mountains than the Changbai Mountains.
