影响群落组成与结构的因素

Factors that Affect Community Composition and Structure

摘要:

摘要：生物群落是特定空间特定环境下不同生物种群的集合，它是基于生物对环境的依赖、在种群间的相互作用与协同进化中逐渐形成的。由于受生物因素（主要是捕食和竞争）、干扰、和空间异质性等因素的影响，它的存在、组成及结构都随着环境条件的改变在空间和时间上不断的变化着。

Abstract:

Abstracts:Biotic community is a collection of different biological species under particular space and circumstances, which forms gradually on the basis of biological dependence on the environment, the interaction and co evolution among species. Due to biological factors (mainly predation and competition), interference, spatial heterogeneity and other factors, its presence, composition and structure change with the environmental conditions in space and time.
