Abstract

Abstract: The population and community characteristics of Brasenia schreberi in Shuangpu town of West Lake, Hangzhou were surveyed using quadrat method and α-diversity index. The main results are as followsten plant species belonging to eight families and ten genera occur in this community. The vegetation was called B. schreberi-Hydrilla verticillata Ass. α-diversity index analysis revealed that Simpson index（D）, Partrick’s richness Index（R）, Shannon-Wiener diversity index（H′）, Pielou’s evenness index（J） and Simpson’s ecological dominance（SN） were 0.719, 10, 1.684, 0.731 and 0.242, respectively, indicating low levels of species diversity at the B. schreberi community. Excessive cultivation and frequent picking might be the most important cause of low levels of species diversity in B. schreberi community.

Key words: Brasenia schreberi, endanger, α-diversity index, species diversity, West Lake
