| 摘 要： | 对狮子关库区森林群落演替过程和结构动态进行了研究。结果表明：1）演替过程包括从针叶林阶段，以针叶树为主的针阔混交林阶段到顶极常绿阔叶林阶段等6个过程；2）演替过程中不同群落的物种多样性和均匀度呈现规律性变化；3）演替主要标志体现在乔木林层优势树种的更替和物种分布格局的变动方面。

| Abstract: | This paper studies the succession procedure and organization dynamics of forest community with several dominant tree species. The results show that: (1) The succession process includes 6 stages, from coniferous forest stage,with a mixture of both coniferous and broadleaf trees but taking the coniferous tree as the dominant component to climax stage;(2)The species diversity index and community eveness of the several forest community change regularly in different succession processes.(3)Both dominant tree species alternation and spatial pattern are the main index for succession. |
