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。
Biotic community is a collection of different biological species under particular space and circum- stances, 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 environmen- tal conditions in space and time.
