Riparian areas have important ecological, social, economic and tourist value Ecological rehabilitation of degraded riparian ecosystems has become a topic of intense interest worldwide Taking ecology, geomorphology and hydrology as a basis, riparian studies involve a wide range of disciplines and technologies, but however, studies on basic theories and methods of degraded riparian ecological rehabilitation in China are very poor, and as a result, the primary concepts and problems have not been uniformly recognized.Therefore, in this paper, the author discusses the theoretical basis of ecological rehabilitation in riparian areas in the light of the actual scientific research practices carried out in the past six years The riparian concept, riparian vegetation functions, scale of range and time of ecological rehabilitation are defined and the significance,contents,riparian management concerning research on ecological rehabilitation in riparian areas are discussed as well by taking Qianshui riparian beach land at the foot of Tianzhu Mountain as a case In order to explore an approach to rebuild riparian beach land areas of Qianshui river in Anhui province,we planted five tree species on trial which were divided into two experimental design types. Through the analysis on the ecological and economic functions of reestablishment of riparian beach land,the experimental results showed that the influence of reestablishment on river flow,soil physical and chemical properties,soil fertility,soil texture and silt ation in different reestablishment measures and the stability of riparian zone is very significant
