摘　　要：以井冈山云锦杜鹃群落10个样地调查资料为基础,对该群落的物种组成、区系成分、群落结构和物种多样性进行研究。结果表明:该群落有维管植物44科67属83种,其中蕨类植物有6科6属6种,裸子植物4科4属5种,被子植物34科57属72种;区系分析显示,该群落植物区系地理成分复杂,热带性成分和温带成分均占较大比例;群落为复层异龄结构,云锦杜鹃、交让木和猴头杜鹃是组成该群落的建群种;物种多样性分析显示,群落Simpson指数和Pielou指数较高,Shannon-Wiener指数和物种丰富度指数较低,物种多样性指数在样地间有一定差异,在群落不同层次未表现出一致的变化规律。The species composition,floristic elements,community structure and species diversity of Rhododendron fortunei communities in Jinggang Mountain were analyzed,according to the statistics from 10 sample plots.The result showed that there were 83 species of vascular plants in these communities of Rhododendron fortunei（including varieties）,belonging to 44 families and 67 genera,in which the pteridophyte accounted for 6 families,6 genera and 6 species,the gymnosperm 4 families,4 genera and 5 species,and the angiosperm 34 families,57 genera and 72 species.The floristic analysis showed that the flora geographical elements were complex,the tropicail element and temperate element took a large proportion.Communities of Rhododendron fortunei was many storied all-aged forest,Rhododendron fortunei,Daphniphyllum macropodum and Rhododendron simiarum were the constructive species.The Rhododendron fortunei communities in Jinggang Mountain had high Simpson index and Pielou index,low Shannon-Wiener index and Richness index.There were some differences of species diversity among plots,and the variation patterns of species diversity index which was ever used were discordant among layers.
