Species Diversity of Rock Plant Community in Danxia Landform of Zhejiang Province

In order to provide scientific basis for vegetation and biodiversity conservation,species diversity of rock plant in Danxia landform of Zhejiang Province was analyzed in this study.According to the results,there were 195 species belonging to 143 genera and 82 families.The changing trend in Margalef index,Simpson index and Shannon-Wiener index of the same community in different layers was the same,namely herb layer>shrub layer>moss layer>liana layer;the order of Pielou index was moss layer>liana layer>herb layer>shrub layer.Comparing species diversity in different regions,we found that the index of all layers on Jianglang Mountain was higher except the moss layer.
