摘　　要：基于对22个样地,共计11000m 2面积的群落调查,以群落样地中乔木层树种的重要值为指标,探讨了格氏栲自然保护区常绿阔叶林组成类型及其物种多样性。结果表明,该保护区常绿阔叶林可分为格氏栲林、米槠林、甜槠林、刨花楠林、沉水樟和苦槠林、观光木林、闽楠林等7个类型,不同类型的植物组成成分和物种多样性变化较大;常绿阔叶林群落的物种多样性表现为灌木层>乔木层>草本层。Based on the survey at twenty two sample sites with total area of 11000 m^2, this article examines the types of the evergreen broadleaf forest and their community species diversity in Castanopsis kawakamii Nature Reserve with the important values of medium tree layer in these sites as the index. The findings show that the evergreen broadleaf forest can be divided into seven types, which are Castanopsis kawakamii forest, Castanopsis carlesii forest, Castanopsis eyrei forest, Machilus pauhoi forest, Cinnamomum micranthum and Castanopsis sclerophylla forest, Tsoongiodendron odorum forest, and Phoebe bournei forest. The species diversity index varies with the types of the community. The species diversity index is shown as shrub layer〉tree layer〉 herb layer in the broadleaf forest community.
