缙云山草珊瑚群落特征研究

Study on the Community Characteristics of Sarcandra glabra on Mt.Jinyun

通过对草珊瑚群落特征进行研究和分析,结果表明:该群落种类组成丰富,共有种子植物77种,分属37科62属,区系组成复杂,从科属的地理成分看,热带分布型明显多于温带分布型,表明该区系具有较明显的热带、亚热带性质,并具有一定的温带性质.群落的生活型以高位芽植物为主,地上芽植物次之.群落叶的性质以小型和中型叶、单叶、全缘、革质和草质叶的种类为主.群落垂直结构较复杂,可分为乔木层、灌木层、草本层,并且有一定数量层间植物.

A study of the features of Sarcandra glabra community on Mt. Jinyun showed that its species composition was abundant： there were 77 species of seed plants in the community, belonging to 37 families, 62 genera. The floral corlaposition of S. glabra community was complicated. In terms of family and genus geographical elements, many of them were distributed in tropical zones more than in temperate zones, demonstrating that the flora had tropical and sub-tropical features, with some temperate features, though. The life-form phaenerophytes in this community occupied the dominant status, followed by the chamaephytes. The features of the community leaf were mainly microphyll and mesophyll, simple, entire, coriaceous and herbaceous. The vertical structure of the community was complicated, which was divided into three layers： arbor layer, shrub layer, and herb layer. There were some interstratum plants in the community.
