山东栎林的物种多样性

RESEARCH ON THE SPECIES DIVERSITY OF THE ASSO.Quercus Spp.IN SHANDONG

本文采用了 Simpson.Shannon-Wiener 和 PIE 三个物种多样性指数及以前两者指数为基础的均匀度公式,研完分析了山东栎林的物种多样性.其结果表明:物种多样性明显地反映了栎林的类型、结构、动态以及生境条件等特征:在反映栎林组织结构水平时,以 Shannon-Wiener 指数相对较佳.

This paper analyses,by using three diversity indexes(Simposon, Shannon-Wiener and PIE)and the evenness indexes based on Simpson and Shannon-Wiener,the species diversity and the species evenness of the Asso.Quercus spp.in Shandong.The preliminary results make known that the species diversity mirrors clearly the type,structure, dynamic status and ecological environment of the oak forest.Shannon- Wiener index is better than the others in the aspect of reflecting its organization.
