摘要
对南岳1 500m2样地的小红栲群落的物种组成、区系成分、结构特征及物种多样性进行了统计和分析。结果表明:该群落共有维管植物42科65属78种,其中蕨类植物4科4属4种,裸子植物2科2属2种,被子植物36科59属72种;群落垂直成层明显,分为乔木层、灌木层、草本层和层间植物,其中乔木层种类最少,灌木层物种最丰富。植物区系地理成分较复杂,热带性成分占60.67%,温带性成分占32.79%,具有明显的热带、亚热带性质;物种多样性分析显示该群落多样性指数偏低,多样性复杂程度由高到低的顺序为灌木层、藤本层、草本层。
The species composition,flora,community structure and species diversity of Castanopsis carlesii community were analyzed based on the community investigation in 15 plots in Nanyue.The results show that 78 species in 65 genera of 42 families of vascular plants were recorded,in which pteridophytes accounted for 4 species in 4 genera of 4 families,gymnosperms 2 species in 2 genera of 2 families and angiosperms 72 species in 59 genera of 36 families;the community can be divided into arborous layer,shrub layer,herbaceous layer and liana,in which the arborous layer has the least species in number but the shrub layer the most;the floral geographic elements are complex,in which the tropical floristic elements accounted for 60.67% and the temperate floristic elements 32.79%;the values of species diversity indices are comparatively low and the species diversity order from high to low value of diversity index is shrub,liana,herb and arbor.
