摘要： 对江苏云台山三桠乌药群落结构首次进行全面调查。研究表明，三桠乌药群落共有维管植物89科213属300种；群落垂直结构明显，可分为乔木层、灌木层和草本层；乔木层中壳斗科植物的重要值高；灌木层中三桠乌药重要值最大；草本层中求米草重要值最大；群落中物种Raunkiaer频度等级分布为A>B>C>D>E；各层次Margalef丰富度指数是草本层＞灌木层＞乔木层，Simpson指数和Shannon-Wiener指数均是草本层＞乔木层＞灌木层，Pielou均匀度指数是乔木层＞草本层＞灌木层；群落维管植物区系总体上表现出由热带至亚热带向温带的过渡性。

Abstract: The aim of this study is to imestigate the community structure of Lindera obtusiloba completely for the first time, and the result showed that the community was of a clear vertical structure, including 300 species, belonging to 213 genera and 89 families in total. It was composed of arbor layer, shrub layer and herb layer, in which the importance value of Fagaceae, Lindera obtusiloba and Oplismenus undulatifolius was the largest, respectiuely. The rank distribution of Raunkiaer frequency was A>B>C>D>E. Among all layers of the community, Margalef richiness indexes were herb layer＞shrub layer>arbor layer, Simpson and Shannon-Wiener indexes were herb layer>arbor layer＞shrub layer, and Pielou evenness indexes were arbor layer>herb layer＞shrub layer. The floristic composition shows a transition from tropic to sub-tropic and temperate.
