摘　　要：河流滨岸带在净化水体、截留污染、景观休闲等方面起着极为重要的作用。为了分析鄱阳湖五河不同河段滨岸带的生态水利功能,从自然功能和社会功能两大方面构建了滨岸带功能分类体系,综合运用遥感、GIS等空间信息技术,对鄱阳湖五河典型河段的滨岸带进行了地表覆盖解译和功能分区,进一步分析鄱阳湖五河典型河段滨岸带现状及横纵向的空间差异。基于典型河段滨岸带现状分析,探讨了滨岸带生态水利功能在河流纵、横向上的空间分区,最终结合不同河流不同河段的特点给出针对性的生态水利治理建议,为实施流域生态保护与生态建设的分区管理、区域产业布局、生态防灾减灾、环境保护与建设规划等提供科学依据。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.
