Comparative Analysis on the Species Diversity of Quercus Phillyraeoides Community in Different Districts
Quercus phillyraeoides community is one kind of evergreen sclerophyllous forests distributing widely in the subtropic mountains of China, which has very important value in studying on flora, ecology and paleobotany.Based on the field investigation, the species diversity of Quercus phillyraeoides communities in 5 districts was comparatively analyzed by means of species richness, diversity indices, evenness index and community dominance, and the relationship between diversity and environmental factors was discussed.The results showed that shrub layer had higher diversity than tree layer in different communities, and tree layer had better evenness by the value of Alatato.All of the indices could indicate the condition of the diversity.The model of abundance distribution indicated that the species distributions of tree layers were log series and several of shrubs were geometric.Pearson correlation between diversity indices and main environmental factors indicated that temperature was the key factor to impact the community diversity.
