The riparian zone of river plays a crucial role in purifying water bodies,intercepting pollution,and recreating landscape. To analyze the ecological water conservancy functions of the riparian zones of five rivers in the Poyang Lake area,the functions of river's riparian zone are summarized into two categories: natural function and social function. Furthermore,the surface coverage and functional zoning of the riparian zone of the five rivers are interpreted using remote sensing and GIS. The current status of the riparian zone is introduced,and the spatial difference in vertical and horizontal scales are analyzed. On such basis,the spatial zoning of water conservancy functions in horizontal and vertical directions of the rivers is discussed,and finally some targeted ecological water conservancy measures are put forward according to the characteristics of different river sections. The research is expected to offer scientific basis for the implementation of zoning management,regional industrial distribution,ecological disaster prevention and reduction,environmental protection and construction planning for watershed's ecological protection and ecological construction.
