广西红树林类型及生态

广西红树林植物22种(隶属14科21属)。根据生态、外貌原则划分为10个群系19个群落。各类型在滩涂上的生态序列,从外滩(低潮线)、经中滩、至内滩(高潮线)、到潮上线(海岸),依次分布海榄雌林、秋茄林、桐花树林、红海榄林、木榄林和海岸半红树林。这是各滩位的土壤质地、养分、盐度等环境因子与红树林建群植物生态特性相结合形成的,也是各类型红树林的形成和发展的演替过程。

THE TYPES AND ECOLOGY OF MANGROVE IN GUANGXI AUTONOMOUS REGION

There are 22 species of mangrove belonging to 21 genera and 14 families in Guangxi. According to the ecological and physiognomical principles. they may be divided into 19 communities and 10 formations. The ecological series are composed of Avinnia marina, Kandelia candel, Aegiceras corniculaturn, RhinoUplwra, tylosa and Bruguiera gyinievrrhiza formations as well as coast semimangrove, which distribute in turn from outside beach(low tidal line),inside beach(high tidal line)to coast(above tidel line). This is the result of the ecological characteris tics of dominant plants of mangrove combined with environment factors(e. g. soil texture, nu-trient, salt content, etc.), and also is a succesion process of forming and developing of various types of mangrove.
