摘　　要：消落带是一种具有多种功能的生态资源,但又极易遭到破坏,因此对消落带的信息提取和利用具有重要生态意义。作者基于三峡水库高、低水位期环境减灾卫星的CCD数据,利用遥感解译开展了三峡水库重庆段消落带信息提取,分析了其空间分布特点,掌握了消落带消涨的空间分布。研究表明长江三峡重庆段的消落带总面积为77.61km^(2),消落带面积从大到小依次为万州、忠县、奉节、丰都、云阳、涪陵、巫山、石柱。The fluctuating zone is a kind of ecological resource with multiple functions,but it is easy to be destroyed,so it is of great ecol-ogical significance for the information extraction and utilization of the fluctuating zone.Based on the CCD data of the environmental disaster reduction satellite during the high and lowwater level periods of the three Gorges Reservoir,the author uses remote sensing in-terpretation to extract the information of the fluctuating zone in the Chongqing section of the three Gorges Reservoir,analyzes its spatial distribution characteristics,and grasps the spatial distribution of the fluctuating zone.The study shows that the total area of the fluctu-ating zone in the Chongqing section of the three Gorges of the Yangtze River is 77.61km^(2),and the fluctuating zone area from large to small is Wanzhou,Zhongxian,Fengjie,Fengdu,Yunyang,Fuling,Wushan and Shizhu.
