Due to the impacts of human activities such as water resources exploration and pollution,the physical and chemical conditions of rivers,such as substrate,water quantity and quality,are prone to change,which directly and indirectly affect the survival of aquatic organisms such as plankton and macroinvertebrates.Therefore,the stability of river habitats is the key to protect aquatic organisms.However,current research on the habitat stability of river ecosystems is relatively scattered,especially insufficient on the concept,evaluation indicators,and methods.This limits the accurate assessment,which directly affects the engineering implementation and scientific management of river protection and restoration.This study systematically reviews relevant research on river habitats and proposes the concept of habitat stability.Firstly,the relationship between habitat and habitat stability were discussed,and then the differences between habitat stability and ecosystem stability were compared.Furthermore,habitat stability was analyzed from three dimensions:diversity,integrity,and suitability.Secondly,we compared common river habitat evaluation models and analyzed the impact of habitat stability on aquatic organisms.Thirdly,we analyzed river habitat restoration from five aspects:water environment governance,connectivity restoration,riparian restoration,ecological regulation,and community restoration.Finally,we provided some suggestions for a future research on the topic of river habitat stability.
