摘  要:
采用样方法对安徽天堂寨自然保护区的珍稀濒危植物领春木群落结构特征进行了调查研究。结果发现,在领春木群落样方中,共有高等维管植物77种,隶属于48科71属;领春木垂直结构可分为乔木层、灌木层、草本层;群落中领春木的重要值为131.65%,显著高于其他树种,为群落中绝对优势种;其物种多样性指数不高,群落的Simpson指数、Shannon-Wiener指数和群落均匀度分别为0.8466,2.4974和0.7099,应加强领春木自然群落人工保护和管理,以防该物种生态系统再度遭到破坏。

摘  要:
The community structure of rare and endangered E.pleiosperma in Tiantangzhai Nature Reserve in Anhui province was studied by the method of plot.The result showed that the community was composed of 77 vascular plant species,belonging to 48 families,71 genera in the plots.And the community structure could be divided into arborous layer,shrub layer and herbaceous layer.E.pleiosperma occupied predominant position in this community and its importance value reached to 131.65 %.Species diversity indexes was relatively low,and their Simpson index,Shannon-Wiener index and Evenness index were 0.846 6,2.497 4 and 0.709 9 resp.Artificial protection and management should be strengthened for the E.pleiosperma natural community and the ecosystem should be avoided to being destroyed continually because of their unstable community.
