摘　　要：以三峡水库为代表的长江上游大型梯级水库运用后,极大的改善了长江防洪、发电和航运能力,促进了流域社会经济高质量发展。三峡水库是我国重要淡水资源战略储备库,其岸线的科学保护、合理利用对保护库区生态环境和促进社会经济发展有着重要意义。然而,人们对于大型水库岸线的保护和利用状况及其耦合协调发展水平长期缺乏关注。由此,以三峡水库为例,首先构建岸线保护与利用耦合协调度评价指标体系,根据8个关键指标进行定量评价;其次结合遥感影像、野外采样数据,运用耦合协调度模型对34段岸线的保护与利用耦合协调空间分布特征进行分析和讨论。研究结果表明:(1)三峡水库岸线利用水平和综合水平从水库上游至下游呈递减趋势,且岸线保护水平均值为0.523,大幅度高于岸线利用和综合水平。(2)三峡水库岸线保护与利用的耦合协调度主要分布在0.161~0.879区间,有44%的岸线位于磨合发展区中,协调发展程度为初级水平。(3)耦合协调度的空间分布特征由库区西部向东部呈现递减趋势,与社会经济发展水平存在一定的联动性。为此,我们提出今后要以岸线保护为主、同时需重视岸线利用的效率,促进岸线保护与利用的协调发展。结果有望为三峡水库岸线资源的保护与利用协调发展提供参考,助力长江上游梯级水库可持续运行。The operation of large cascade reservoirs in the upper Yangtze River has significantly improved the capacities of flood controlling,power generation and shipping of the Yangtze River,which in turn,promoted the regional socio-economic development.This is specially the case for the Three Gorges Reservoir(TGR).The TGR is one of the strategic reserves of freshwater resources in China.Protection and utilization of its waterfront resources in a scientific and effective way are of great significance for ecological environment protection and social economic development around reservoir areas.However,too little attention has been paid to coupling coordination of protection and utilization of waterfront resources along large reservoirs in the upper Yangtze River.Therefore,taking the TGR as an example,firstly,an array of assessment indexes has been carefully established for assessing the protection and utilization of the waterfront resources in the TGR.It consists of eight indicators which can be quantitatively evaluated.Secondly,with the help of remote sensing images and field sampling data of 34 sections in the TGR,a coupling coordination degree model is applied to the assessment indexes for assessing the coupling coordination of protection and utilization in the TGR.The results show that:①The shoreline utilization level and comprehensive level of the TGR show a decreasing trend from the upstream to the downstream of the reservoir,and the average shoreline protection level is 0.523,which is much higher than the shoreline utilization and comprehensive level.②The coupling coordination degree of the protection and utilization of the waterfront is mainly distributed in the range of 0.161~0.879,and 44%of the shoreline is located in the running-in development area,and the coordination development level is at a primary level.③The coupling coordination degree shows a“high in west and low in the east”distribution pattern,indicating that there is a certain linkage with the level of social and economic development.Therefor
