摘　　要：根据样地调查资料,分析了云南哀牢山徐家坝地区群落物种组成、区系特点、群落层次结构及生态外貌特征。结果表明,在1hm2固定样地中,共有维管束植物166种,隶属77科138属,植物的科属组成丰富。群落内区系成分复杂,热带区系成分高于温带区系成分。群落成层现象明显,可分为乔木层、灌木层和草本层3个层次,层间植物非常丰富。群落的生态外貌主要由中叶、单叶、革质、非全缘为主的常绿高位芽植物所决定。无论从区系地理成分组成还是群落结构和生态外貌上均体现了中山湿性常绿阔叶林的特征。A survey was conducted to study the community composition,floristic features,community structure and eco-physiognomy of the evergreen broad-leaved forest in Xujiaba,Ailao Mountains according to the data of a sample plot of 1 hm2.A total of 166 species of vascular plants were recorded,which belong to 77 families and 138 genera.The species composition is abundant in terms of family and genus.The community had a complex floristic composition,and the tropical elements were more than the temperate elements.The community had three conspicuous layers,which were arbor layer,shrub layer and herbage layer.The richness of interlayer plants was very high.The eco-physiognomy of the community was mainly determined by evergreen phanerophyte species with un-entire,conaceous,single lamina.The evergreen broad-leaved forest in Xujiaba is a typical middle-mountain moist evergreen broad-leaved forest in terms of community composition and structure,floristic features,and eco-physiognomy.
