以梵净山国家级自然保护区天然任豆(Zenia insignis)群落为调查研究对象,分析了群落的物种组成、外貌和结构特征,定量分析了群落主要树种的特征指标.结果表明,梵净山任豆群落共有植物29科41属47种,垂直结构明显,分为乔木层、灌木层、草本层,乔木层的物种多样性指数较高,物种丰富,任豆在群落中处于优势种地位,但因缺乏更新层,在自然种群中,属于一个衰退种,整个群落将逐渐演替为常绿阔叶林.%Investigations were conducted on Zenia insignis community in Fanjingshan National Nature Reserve, including species composition, macroscopic features and structure feature. Feature index of main species in the community were analysed quantitativly. The results showeded that there weare 47 species of 41 genera belonginging to 29 families in Z insignis Chun community plant in the Reserve. Vertical structure wais obvious, tree, shrub and herb layer, there wereare higher the species diversity index and abundant species in the tree layer. Z insignis Chun is a dominant species in the communities.itcommunity and is a recession species in natural population because of no lack of renewal layers,thelayer, so the whole community will be gradually succession tofor evergreen broad-leaved forest.
