摘要
人类活动和气候环境对淡水生态系统的影响越来越显著.细菌通常占淡水生态系统中微生物总量的90%以上,淡水生态系统中细菌群落多样性和群落结构的改变显著影响其在生物地球化学过程和生态动力学中的作用.通过对比不同淡水生态系统(河流、湖泊等)、不同环境介质(水体、沉积物、河岸土壤等)中细菌群落多样性和结构,分析了影响细菌群落结构的物理化学因素,介绍了现有研究细菌群落的分子生物学方法.已有的研究表明,未来还需对多种淡水生态系统和其他环境介质中的细菌群落展开系统测量和研究,为环境监测和保护淡水生态系统提供基础信息.
Abstract
Human activities,climate and environment affected freshwater ecosystems significantly.More than 90%of microorganisms in freshwater were bacteria.Changes in the diversity and structure of bacterial communities in freshwater ecosystems affected the roles of bacteria in the biogeochemical process and eco-dynamics.In this review,the diversity and structure of bacterial communities in dif-ferent freshwater ecosystems(rivers,lakes,etc.)and different environmental media(water bodies,sediments,riparian soils,etc.)were compared.The physicochemical factors affecting bacterial community diversity and structure were analyzed.Molecular biological methods for studying bacterial communities were introduced.Present studies indicated that the diversity and structure of bacterial com-munities in freshwater ecosystems and other environmental media should be studied systematically to provide necessary information for environmental monitoring and freshwater ecosystem protection.
