浙江古田山自然保护区青冈林植物物种多样性研究

分析了浙江古田山自然保护区青冈林的植物区系组成和群落物种多样性。结果表明，8个样地中共有维管束植物147种(含变种)，隶属51科92属。其中蕨类植物5科7属14种，裸子植物1科1属1种，被子植物45科84属132种。青冈林植物区系成分复杂，具有较高的热带成分比例。群落科、属、种组成多样性较高，植物种类丰富，组成复杂。群落垂直结构中，物种多样性依灌木层→乔木层→草本层的次序递减，乔木层、灌木层的物种多样性指数明显大于草本层。

Plant species diversity of Cyclobalanopsis glauca forest in Gutian Mountain Nature Reserve of Zhejiang province

The floristic composition and the species diversity of Cyclobalanopsis glauca forest in Gutian Mountain Nature Reserve of Zhejiang province were analyzed. According to the statistics of 8 plots, there are 147 species (including varieties) of 92 genera and 51 families in total, including 14 species of 7 genera and 5 families in Peridophyte, 1 species of 1 genus and 1 family in Gymnospermae and 132 species of 84 genera and 45 families in Angiospermae. The floristic elements are complex, and the total of tropical distribution type in generic level amounts to 55.56%. The community has a high diversity of family, genus and species, and a great variety of plants whose composition is complex. In the vertical structure of community, the species diversity decreases from shrub, tree to herb layer. The species diversity index of the tree layer and shrub layer are obviously bigger than that of the herb layer.
