摘要: 群落物种多样性指数以及群落均匀度、丰富度等指标均能较好地反映亮叶水青冈群落的类型划分、群落结构、生境等特性。也能体现出该群落结构组成的特殊性。群落种-多度分布说明此群落富集种少、稀疏种多,而且这些种的多度有一定的规律性的特征。通过研究说明物种多样性定量指标对于深入研究森林群落的特性具有重要的意义。

Abstract

The species diversity index, evenness and richness of Fagus lucida communities are analysed. The results show that all these indexes well reflect the characters of communities, such as the type classification, structure and habitat. Meanwhile, they also reflect the particularity of composition and structure of the Fagus lucida community. Discussion on the distribution of species abundant shows that the community includes fewer dense species but more sparse species, and the abundance of these species has regularity. It is concluded that the quantitative analysis of species diversity index is significant to make a through study on the forest community.
