The Review on the Research for the Interception Mechanism and Effects of Riparian Buffer Zone

Riparian buffer zone,usually adjacent to rivers（including wetlands and lakes）,is referred to the domain between land and aquatic ecosystem which has buffering functions on pollutants,sediment and flood.It is one of the most important measures for controlling non-point source pollution and protecting water environment.A large amount of researches on different aspects of riparian buffer zone have been carried out.In order to give a detailed summary and systematical review,a framework of researches on riparian buffer zone was built up,which summarized the previous research results on the riparian buffer zone with its mechanism,structure,function and effect,as well as the practices and management.Future research frontiers are also proposed based on the summary and analysis.
