浙江古田山自然保护区木荷群落研究

通过对木荷群落特征进行分析，结果表明：木荷群落植物种类丰富，科属组成分散，区系成分复杂。从属的地理成分来看，热带分布的属多于温带分布的属。群落的生活型以高位芽植物为主，地下芽植物次之。该群落叶的性质以小型叶、单叶、草质、非全缘为主。群落垂直结构复杂，地上成层现象明显，可分为乔木层、灌木层和草本层，并有一定数量的层间植物。乔木层、灌木层和草本层的物种多样性大小依次为灌木层＞乔木层＞草本层。

A STUDY ON THE SCHIMA SIPERBA COMMUNITY IN GUTIAN MOUNTAIN NATURE RESERVE IN ZHEJIANG PROVINCE

The study on the features showed: There are various plants in the community of Schima superba, and its family and genus are of scattered composition. Their florai composition is complicat-ed. In terms of genus geographical elements, many of them are distributed in tropical zones. Accord-ing to Raunkiaer's statistics of life - form, the life - form phaenerophyte of this community numbers first, and the geophyta second. The features of the community leaf is mainly microphyll, simple, her-baceous and unentire. The vertical structure of community is relatively complicated which can be di-vided into tree layer, shrub layer and herb layer as well as a definite number of interstratum plants. The species diversity index of different layers shows: shrub layer > tree layer > herb layer.
