| 摘 要： | 基于华北土石山区潮关西沟流域天然森林植被调查的基础上．对森林植被群落演替中群落树种组成、胸径结构和生物多样性变化进行了研究。结果表明，随着演替的进行．群落的乔灌木树种数先升高后降低，趋于稳定。而乔木密度呈增加趋势，而灌木密度和乔木树种的最大株数比例的胸径范围呈不断降低趋势。群落的乔木、灌木和乔灌木的物种多样性、丰富度随着演替的进行先升高后降低。除了栎树林乔木和平榛灌丛的乔灌木的均匀度较低外，乔木、灌木和乔灌木其他群落的均匀度变化不明显。

| Abstract: | Based on investigation of natural forest vegetation in Chaoguanxigou watershed of rocky mountain area of North of China,the composition of species, structure of DBH of trees and species diversity of trees and shrubs in the course of forest succession are researched. The results show that with succession proceeding, the number of trees and shrubs increased at first, then decreased and trend to stable at last. However the density of trees increased, and at the same time, shrubs density, maxium proportion of tree number of certain DBH range trend to decrease. The species diversity and abundance of trees and shrubs increase at first and begin to decrease in the last period. And the changes of evenness of species in most cases is not obvious in the course of succession. |
