Abstract This paper reviews the adaptive changes of biofilm structure and function under dry and wet stress in river ecosystem, and analyses the dynamic changes of different functional groups (autotrophic and heterotrophic) and community structure (α biodiversity and β biodiversity) in biofilm. The dynamic responses of biofilm productivity and metabolic function under dry and wet stress were systematically summarized. The resistance mechanism of biofilm microbial community to dry and wet stress was analyzed, and the application prospect of molecular ecological network analysis in biofilm dynamic response was prospected.

Key words： intermittent river biofilm community structure functional characteristics network analysis
