群落群落community  群落(C ornmunity)又名生物群落(biotiec。~unity,biocoenose),在一定空间内生活的生物种群的聚合体。群落内的生物具有一定结构和功能,并且相互依存.相互制约。德国莫比乌斯(K .Mobius)1877年最先应用生物群落一词。群落是生态学研究的主要对象之一。根据研究对象,可分为植物群落(planteommunity)、动物群落(animal eornrnunity)和微生物群落(microbiotic co们口rnunit刃等,若限于研究昆虫,可称为昆虫群落(insect eommunity)O 结构指在特定环境下,群落中各生物成分及其相互联系。按照能量在群落中各种生物成员之间流动的方向,可将生物分为生产者(自制养料的植物)、消费者(植食性昆虫等动物为初级消费者,肉食性昆虫等动物为次级、3级、4级消费者)和分解者(分解植物残体和动物尸体的微生物)3类。按照群落中植物所占的空间位置,可区分为冠层、地被层等不同的层次,则与植物相联系的昆虫(植食的或肉食的),也呈现层次结构。群落的外貌特征以群落中的优势种为标志,如稻田群落、麦田群落,显然是以水稻、小麦为优势种群。决定群落结构的因素主要有:①历史因素;②种类库(speeies pool)的大小;③建群者来源的远近;④生活小区(见生境)的大小;⑤种间的相互关系。这些因素可调节群落内生物种类的数量,而种类数量又从属于生活小区内资源的多样性。 功能即群落中物理因素、化学因素和生物因素的综合作用,表现在特定的物质流、能流、信息流、生物量、生物生产力和演替过程等方面,其中物理因素和生物因素研究较多。化学信息是影响群落内生物种间关系和同种关系的重要因素,有时可影响物质流、能流和演替的方式和过程。如寄主植物的抗生性物质(如水稻的r一氨基丁酸对褐稻虱的抗生性);可改变这类寄主植物的昆虫群落种类组成或优势种成分;植食性或肉食性昆虫常借助化学信息标志其领域性,排斥其他昆虫的侵犯;利他素的存在,则促进食物链的形成,或由于第一性害虫的存在,引起次生性害虫发生(见群落演替)。 研究方法常应用梯度分析方法和采用多种指标。梯度分析是通过环境梯度的变化,研究群落结构特征以及群落内的相互联系。在群落的研究中,常用生物生产力、生物最、种的丰盛度、群落多样性指数、群落相似性系数等指标,定量描述和比较不同群落的特征(见群落多样性、群落相似性、梯度分析)。
