Epiphytic community is a complex structure consisting of organisms such as algae,bacteria and fungi,and covers the surface of aquatic macrophytes in most shallow lakes.It has a unique composition and spatial structure,exhibiting significant dynamic characteristics in accordance with different seasons and the growth of submerged plants.Epiphytic community is closely related to the host plants and surrounding water environment,reflecting various habitat factors such as nutrient,light and temperature.It also has different interactions with submerged macrophytes,grazers,phytoplankton and other aquatic organisms.Epiphytic community participates in the material transformation of water ecological system,and plays a vital role in the shift between macrophytedominated and algal-dominated lake ecosystems.Its relatively high primary productivity makes itself to be an important food source for aquatic animals,which results in diverse food webs.Based on previous studies,this article analyzed the species composition and dynamic characteristics of epiphytic community.It can be concluded that epiphytic community is an important component for aquatic ecosystems,and further studies on epiphytic community can provide scientific basis for the restoration of submerged macrophytes in management of eutrophic lakes.
