| 摘 要： | 米槠群落是三明格氏栲自然保护区常绿阔叶林的第二大群落类型。在6个样地，总面积为3000m^2调查资料的基础上，对该保护区米槠群落的植物种类组成、分布区类型和不同样地、不同层次的物种多样性进行了分析。结果表明：米槠群落有维管植物44科74属106种；属的分布区类型以热带成分占优势，温带成分占有一定比例。乔木层、灌木层、草本层的各项物种多样性指标在群落各样地间均有一定的差异；在群落垂直结构中灌木层的多样性指数最大，乔木层次之，草本层最小。

| Abstract: | The community of Castanopsis carlesii is the second largest broad-leave forest type in Nature Reserve of Castanopsis kawakamii, Based on the data collected from six sample plots with an area of 3000m^2, this paper analyses the species composition, the types of distribution and species diversity in different plots and layers of the Castanopsis carlesii community. The results show that the community is composed of 106 species of vascular plant belonging to 44 families and 74 genera. In terms of distribution type, most of them are tropical genera. There are also some temperate-originated species. The diversity indexes of tree layer, shrub layer and herb layer among various sample plots are somewhat different. The diversity index of shrub layer is the highest, while that of tree layer and herb layer is the second and the lowest in the vertical structure of the community. |
