Plant Diversity Analysis of Wild Abies Chensiensis Community in Quanbao Mountain

Abies chensiensis Tiegh. is a large evergreen tree belonging to the Abies genus in the Pinaceae family. It is a species endemic to China and a second-class protected wild plant. It is also a vulnerable (VU) plant under the International Union for Conservation of Nature (IUCN). The species diversity of wild Abies chensiensis community in Quanbao Mountain of Henan Province was studied by sample plot survey method. The results showed that there were some differences in species richness index, diversity index and evenness index of the community, which were obviously affected by community type and community structure, and the more complex the community structure was. The greater the species richness index and diversity index, the smaller the evenness index; there are some differences among the species diversity indexes of different life forms of Abies chensiensis community. However, the difference is not necessarily statistically significant.
