摘　　要：就地保护鱼类生境是保护鱼类多样性最为有利和有效的方法。双江口水电站位于大渡河上游,是国家规划建设的重点项目,该工程建设将淹没裂腹鱼和鮡科等鱼类栖息地。从工程实际和鱼类栖息地保护要求出发,采用层次分析法对鱼类栖息地进行比选,选择"梭磨河+茶堡河河口"方案作为鱼类栖息地保护推荐方案,并设计恢复河流连通、建造人工产卵场和生境再造等措施以恢复鱼类栖息地生境,为鱼类栖息地选择和设计提供参考。In-situ conservation of fish habitats is the most beneficial and effective way to protect fish diversity. Shuangjiangkou hydropower station, a key state construction project, is located at the upper reaches of Dadu River. The construction poses the danger of submerging Schizothoracinae and Sisoridae habitats. In accordance with the fish habitats protection requirements, and catering to the project itself, this paper compares the fish habitats by analytic hierarchy process, and selected ＂Suomo River and Estuary of Chabao River＂ as the protection plan. It also takes such measures as restoring river connectivity, constructing man-made spawning ground and habitats reconstruction in order to recover fish habitats. It seeks to provide a reference for the selection and design of fish habitats.
