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.
