| 摘 要： | 以福建三明常绿阔叶次生林为研究对象，选择16块样地，分别测定物种组成、重要值、物种多样性指数，并分析多样性指数与群落演替之间的关系。结果表明，调查样地内共有植物物种57科109属169种。按乔木的优势种16块样地划分为6种森林类型，分别为米槠林、苦槠林、拟赤杨林、黄樟林、栲树林和枫香林，Simpson指数排序为栲树林>枫香林>拟赤杨林>苦槠林>黄樟林>米槠林。结合主要树种的生物学特性将6种森林类型进一步归并为栲类林、拟赤杨林及其他（黄樟林、枫香林）等3种类型。其中，黄樟、枫香林的多样性最高，栲类林次之，拟赤杨林的最小。根据在演替过程中多样性有先增加后降低的变化趋势，将研究区的阔叶次生林划分为3个演替阶段，拟赤杨林为演替的较早期，枫香、黄樟林为中期，栲类林为演替的后期阶段。

| Abstract: | This paper studied species composition, important value and species diversity index and analyzed the relationship between diversity index and community succession of evergreen broad-leaved secondary forests occurring in Sanming , Fujian Province. Sixteen plots representing 6 types of forests were chosen. There were totally 169 vegetation species belonging to 57 families, 109 genera in all plots. The sequence of Simpson index of 6 forest types was Castanopsis fargesii > Liquidambar formosana > Alniphyllum fortunei > Castanopsis sclerophylla > Cinnamomum porrectum > Castanopsis carlesii. The 6 kinds of forest types were furthered grouped into three kinds of forest types based on biological characteristics of the main tree species. The diversity index sequence for these 3 kinds was Cinnamomum porrectum and Liquidambar formosana > Castanopsis >Alniphyllum fortunei. In the community succession, the species diversity increased first and then decreased. According to this trend, the succession for the broad-leaved secondary forest in study areas was divided into three stages: early stage (Alniphyllum fortune), middle stage (Cinnamomum porrectum and Liquidambar formosana forest) and late stage (Castanopsis forest). |
