摘　　要：在江西九岭山国家级自然保护区设置了永瓣藤9个天然群落调查样地,对天然群落物种多样性进行调查,统计分析群落各层次的物种组成,计算其重要值、物种多样性指数,并结合物种多样性与海拔关系进行耦合。结果表明:(1)永瓣藤天然群落共有维管植物39科51属60种,杉木为该群落中的优势种,永瓣藤次之;(2)群落中乔木层、灌木层、草本层和藤本层的各项物种多样性指标在群落各样地间有一定差异,但不显著;在群落垂直结构中,多样性指数大小依次为灌木层>乔木层>藤本层>草本层;(3)永瓣藤在藤本层的重要值为62.78%,位居首位,占绝对的优势地位;(4)物种丰富度、Pielou均匀度指数、Simpson指数和Shannon-Wiener指数与海拔均无显著相关性。永瓣藤目前在群落中具有较高的生态位,群落中物种间竞争不显著。A total of 9 natural community survey sites with Monimopetalum chinense were set up in Jiulingshan National Nature Reserve of Jiangxi Province,and the species diversity of the natural community was investigated and analyzed.The species composition at each level of the community was statistically analyzed,and its important value and species diversity index were calculated,and the relationship between species diversity and altitude was coupled.The results showed that:(1)There were 60 species of vascular plants in 39 families,51 genera,and Cunninghamia lanceolata was the dominant species in the community,followed by M.chinense.(2)The species diversity indexes of tree layer,shrub layer,herb layer and woody climber layer in the community were different,but not significant.In the vertical structure of community,the diversity index was shrub>tree>woody climber>woody climber.(3)The importance value of M.chinense in the woody climber layer was 62.78%,ranking the first place and occupying an absolute dominant position;(4)Species richness,Pielou evenness index,Simpson index and Shannon-Wiener index was no significant correlation with altitude.There was a high ecological niche in the community,and the competition between species was not significant.
