| 摘 要： | 摘要：采用群落多样性指数中Shannon Wiener多样性指数、丰富度指数、Pielou均匀度指数及群落相似性指数中的Jaccard指数和Sorenson指数，对河北省承德接坝地区5种生境条件下金莲花(Trollius chinensis)群落进行比较。结果表明,林中空地、湿地、沟谷、荒坡及林下5种生境类型金莲花群落共包括36科、93属、182种，林中空地物种数最多，林下物种数最少。各群落的物种生态类型均表现为湿生植物多于旱生植物，反映了金莲花喜湿的特性。Shannon Wiener多样性指数表现为林中空地>沟谷>湿地>荒坡>林下，丰富度指数表现为林中空地>湿地>沟谷>荒坡>林下，均匀度指数表现为沟谷>林中空地>荒坡>湿地>林下。群落相似性比较表明，湿地和林中空地两种生境差异性最小，林下和沟谷差异性最大，群落相似性的比较结果与群落多样性的方差分析结果较为一致。土壤水分与光照是影响金莲花群落物种多样性及群落相似性的主要因子。

| Abstract: | The Shannon-wiener index,richness index,Pielou evenness index,Jaccard index,and Sorenson index were used to investigate communities of Trollius chinensis grown in five different habitats in Chengde of Hebei Province.The results showed that 182 plants species in 93 genera of 36 families were found in five different habitats;including forest open space,wetlands,valleys,slope lands and understory.There were the highest number of species in the forest open space and the lowest number in the understory.The hygro... |
