摘　　要：在浙江开化王山阔叶林采种基地群落学调查基础上,根据每个样地内重要值大于1.0的102种木本植物的具体数据,对31个样地群落类型进行聚类分析,并对各样地木本植物的物种多样性和物种丰富度指数进行分析。结果表明:(1)王山采种基地木本植物群落类型主要可分为甜槠林、拟赤杨林、短尾柯林、乌楣栲林、木荷林、马银花林、红楠林、钩栲林、杉木林9个类型,总体以常绿落叶林为主,也有少量常绿落叶阔叶混交林和人工杉木林。(2)物种多样性指数(Shannon-Weiner指数)和物种丰富度整体表现出相似趋势,即乔木层>灌木层;不同群落类型中乔灌两层的多样性指数有一定差异。Cluster method is used to classify 31 plots via analyzing the importance value of 102 tree species, while biodiversity analysis are also used to clarify the development status of these forest plots. The results showed that： （1） Communities of Wangshan forest can be classified into nine groups, the most dominant species are Castanopsis eyrei, Alniphyllum fortunei, Lithocarpus harlandii, Castanopsis jucunda, Schima superba, Rhododendron ovatum, Machilus thunbergii, Castanopsis tibetana and Cunninghamia lanceolata respectively, most of them are belonged to evergreen broad-leafed forest, some of them are mixed evergreen ＆ deciduous forest or man-made forest. （2） Species diversity and species richness indexes are larger in tree layer than that in ground layer and varied between different forest community types. This study will give advanced understanding in the status of Wangshan forest and provide some reference on forest management.
