Abstract: Emmenopterys henryi , an endemic species in China , being one of the grade Ⅱ national key conservation rare and endangered plants . Based on the data collected from sample plots, the community structure features in Dapanshan National Natural Reserve of Zhejiang Province were analysed. The results showed that the companion species of E . henryi were evergreen and from Lauraceae and Camelliaceae . The richness index , species diversity index and evenness index in the E. henryi community were low, but ecological dominance index was high . In the community , dominant life form, dominant leaf size , dominant leaf form, dominant leaf texture was phanerophytes, mesophyll , single leaves, herbaceous leaves respectively and whose percentage was 75.9%, 53.97%, 74.70%, 63.86% respectively. The second leaf sizewas microphyll, whose percentage was 36.51%. The spatial patterns of E. henryi population mostly conformed to clump distribution, and the tree layer could be easily divided into 3 sublayers in terms of height. The regeneration of population of E. henryi was poor and the population size was declining.
