浙江天台山甜槠群落研究

以分布在浙江省天台山的甜储群落为对象,分析了群落的特征和性质。甜储群落中,甜储的优势突出,呈单优势群落。群落垂直结构复杂,可分为乔木层、灌木层、草本层,亦有一定数量的层间植物。乔木层的物种多样性指数偏低,这与特定生境所形成的单优势群落有关。各样地间的植物种类具有较高的相似性,群落内种类组成相对一致。群落内优势种群甜储、木荷的年龄结构属稳定型或增长型,它们在各样地的分布格局均呈集群分布。

A STUDY OF CASTANOPSIS EYERI COMMUNITY AT THE TIANTAI MOUNTAIN IN ZHEJIANG

The community characteristics and quality of Castanopsis eyeri distributed at the Tiantai Mountain of Zhejiang Province are analysed.The Castanopsis eyeri has a striking dominant which shows the monodominant community in the Castanopsis eyeri community.There is complicated vertical structure which can be divided into tree stratum,shrub stratum and herb layer as well as a definite number of interstratum plants.The species diversity index of the tree stratum is a bit low,which has something to do with the monodominant community formed under particular living conditions.There is the very striking similarity of plant species among different plots,and there is a relatively uniform composition of species in the community.The age structures of the dominantpopulation-Castanopsis eyeri and Schima superba belong to stable or increasing type.And the distribution patterns among 10 plots are of clump distribution.
