广西的南桦林和西桦林及其演替趋向

THE SOUTH BIRCH FOREST,WEST BIRCH FOREST IN GUANGXI AND THEIR SUCCESSIONAL TREND

摘要: 在亚热带地区,当常绿阔叶林或山地常绿落叶阔叶混交林被砍伐后,桦木常常迅速侵入并发展成林,构成亚热带落叶阔叶林的～种重要类型,在自然发展过程中,它们又将向原来的森林类型恢复和演变。本文重点介绍广西南桦林和西桦林的一些群落类型及其演替趋向,期待发挥它们在林业建设中应有的作用。

Abstract: South Birch forest and West Birch forest are a seral stage of evergreen broadleaf forest sere,mainly occuring in red and yellow soil mountain of subtropics in Guangxi.Three plant associations are described as follows: Betula austro-sinensis Rhododendron cavaleriei-Indocalamus barbatus Phyllagathis microplectra Association; Betula alnoides-Myrica esculenta-Glochidion eriocarpum-Dicranopteris dichotoma Association; Betula alnoides-Ardisia quinqueqona-Indosasa hispida-Osmunda vachellii Association.Their successional trend of recovering evergreen broadleaf forest can be fully proved through information analysis of species compositions change of community.
