生物群落是占居一定的空间、生活在一个特定的区域或自然生境中的有相似的自然资源需求的一组互相依赖的种群的集合体。它是生态系统中有生命的部分。一个群落的性质是由其中的一个或几个被称为生态优势种的种群所决定的。一个群落的名称除了根据群落占居的自然生境命名(如山间溪流群落、沿海潮间带群落等)之外,也常常根据优势种的名称(如落叶松林,冷杉林群落等)优势种的主要生活型(如热带雨林群落、高山草甸群落等)而定。
Biomes are a collection of interdependent populations of similar natural resource needs that occupy a certain space and live in a particular area or natural habitat. It is a living part of the ecosystem. The nature of a community is determined by the population of one or more of these species, which are referred to as ecologically dominant species. The name of a community is often based on the names of natural habitats (eg, mountain stream communities, coastal intertidal communities) occupied by the community, and often based on the dominant species (eg, larch, fir-fir forest, etc.) The main type of life (such as tropical rain forest communities, alpine meadow communities, etc.) may be.
