摘 要 ：常绿阔叶林是庐山地带性植被，历经近70a的保护和恢复，形成不可多得的既有地带性又有地域特征的植被类型。采用典型群落调查法和每木调查法调查了群落的物种组成、分析了群落的结构特征，通过对木本植物主要种群的结构进行分析，依据各种群径级频率分布规律将群落内物种分为4种类型：扩展种，隐退种，稳定入侵种和随机入侵种。在63种木本植物中，扩展种22种，占总数的34.92%；隐退种18种，占总数的28.57%；稳定入侵种14种，占总数的22.22%；随机入侵种9种，占总数的4.29%。依据这4种类型的物种在群落中的地位和作用，以及它们的生物学和生态学特性，可以判定群落的演替发展趋势，庐山常绿阔叶林正在向顶极演替。

Abstract:Evergreen broad-leaved forest is the zonal vegetation type in Mt.Lushan.After nearly 70 years of protection and vegetation-restoration，a typical vegetation type has been established both with zonal and local characteristics.According to typical community investigation method，this paper investigated and analyzed the species composition and community structure of the forest.Based on the size-class frequency distribution pattern of the population structure of the different tree species，four types was categorized：Expansion，seclusion，enhancing invasion，and randomly invasion.Among the total 63 tree species，there are 22 expansive species，making up 34.92%；18 seclusive species，accounting for 28.57%；14 enhancing invasive species，making up 22.22%；and 9 randomly invasive species，making up 4.29%.It was estimated that the succession trendy of the community based in the analysis of the tree species biological and ecological characteristic，as well as the role and position of the four types of tree species in the forest.The evergreen broad-leaved forest of Lushan is under their succession way to the climax communities.
