摘　　要：采用样方调查法对浙江凤阳山——百山祖国家级自然保护区内的45个样地的物种组成、alpha多样性进行分析。结果表明:各样地乔、灌、草3个层次的Shannon-Wiener指数(H)、Simpson指数(D)和Pielous均匀度指数(Jsw)以五岭坑保护站的米槠(Castanopsis carlesii)、毛锥(Castanopsis fordii)林最高,茶木淤保护站的金钱松(Pseudolarix amabilis)林样地最低;各植物群落类型乔木层的物种丰富度以常绿阔叶林最高;灌木层以针阔叶混交林的物种数最多,草甸样地的灌木物种数最少;草本层则以竹林物种数最为丰富;乔木层各群落的H和D均以常绿阔叶林最高;灌木层的H以针阔叶混交林最高,草本层中各植物群落类型的H、D、Jsw均以竹林最高;在百山祖自然保护区中,常绿阔叶林可以维持较高的木本植物物种多样性,而竹林出现明显纯林化现象,应加以控制。Species composition and diversity was investigated at 45 sample plots in Fengyanshan-Baishanzu Nature Reserve, Zhejaing province byquadrat survey method. The results showed that the highest alpha diversity index was found in the Castanopsis carlesii –C. fordii forest at WLKstation, and the lowest in Pseudolarix amabilis forest at the CMY station. Compared with other vegetation, evergreen broad-leaf forest performed thehighest richness and diversity index at the tree layer. The mixed coniferous broad-leaf forest performed the highest richness index at shrub layer. Inaddition, the bamboo forest performed the highest richness diversity at the herb layer. These results indicated that evergreen broad-leaf forest couldmaintain the higher woody plant diversity and should be protected. While pure bamboo forest dominated by single species should be controlled forthe biodiversity conservation.
