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 different 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 communities in freshwater ecosystems and other environmental media should be studied systematically to provide necessary information for environmental monitoring and freshwater ecosystem protection.

Key words: freshwater ecosystems, bacteria community, diversity, community structure
