摘　　要：千岛湖是截蓄新安江水流而成的山地型人工湖泊,陆域水土流失与水域富营养化问题是导致库区整体生态环境质量下降的两大关键性因素。选取千岛湖人类活动最为频繁的40个河口村镇作为研究对象,聚焦98~118m高程的岸水交接地带,基于水陆耦合协调的视角,探究该地带在生态过程中水土流失与水体富营养化问题的岸水协同生态修复治理方案,旨在解决“岸水空间生态功能区划如何兼顾应对陆域水土流失与水域富营养化两方面生态风险”的关键性水生态修复问题,建立水体治理的长效机制。根据千岛湖正常高水位,以108~118m高程为陆域范围,以98~108m高程为水域范围,基于研究区域的landsat8卫星遥感数据,运用RSEI模型评价陆域水土流失状况,运用FAI模型评价水域富营养化状况,二者耦合协调分析获得水陆生态环境质量的耦合协调发展水平,据此研判关键性水生态问题并分区提出岸水协同生态修复治理措施。结果表明,中度失调河口2个,轻度失调河口2个,濒临失调河口1个,勉强协调河口5个,初级协调河口10个,中级协调河口9个,良好协调河口11个;根据耦合协调发展水平将40个河口村镇划分为三级生态功能区,其中一级生态功能区重点强化治污措施、二级生态功能区重点提高生态韧性、三级生态功能区重点促进价值转换。Qiandao Lake is a mountain-type artifi cial lake made by intercepting the water fl ow of Xin’an River,and the problems of land soil erosion and water eutrophication are two key factors leading to the decline of the overall ecological environment quality in the reservoir area.In this study,40 estuarine villages and towns with the most frequent human activities in Qiandao Lake were selected as the research objects,focusing on the shore-water interface zone of 98~118 m elevation and exploring the shore-water synergistic ecological restoration and management solutions for soil erosion and eutrophication in this zone based on the perspective of coupling and coordination of land and water in the ecological process.The aim is to solve the key water ecological restoration problem of“how to address the ecological risks of soil erosion and eutrophication in the land area”in the ecological function zoning of the shore-water space to establish a long-term mechanism for managing the water body.Accord-ing to the average high water level of the Qiandao Lake,with 108~118 m elevation as the land area and 98~108 m elevation as the water area,based on the landsat8 satellite remote sensing data of the study area,the RSEI model is used to evaluate the erosion status of the land area.The FAI model is used to assess the eutrophication status of the water area.Through the coupling and coordination analysis of the two,the coupled and coordinated development level of the ecological quality of land and water is obtained,based on which the key water ecological problems are investigated,and ecological restoration and management measures for shoreline-water synergy are proposed by zoning.The results show that there are two moderately dysfunctional estuaries,two mildly dysfunctional estuaries,one on the verge of dysfunctional estuaries,fi ve barely coordinated estuaries,ten primary-coordinated estuaries,nine intermediate-coordinated estuaries,and eleven well-coordinated estuaries.The forty estua-rine villages and towns are divided into t
