摘　　要：对拟建小南海水利工程对长江上游珍稀特有鱼类国家级自然保护区的生态影响的预测分析结果表明,保护区72.5km江段的水文情势发生改变,部分江段的结构和功能将遭受严重破坏,胭脂鱼(Myxocyprinus asiaticus)、圆口铜鱼(Coreius guichenoti)、长薄鳅(Leptobotia elongata)等珍稀特有鱼类的产卵场和主要栖息地将直接减少。为最大限度减缓工程建设对保护区的影响,提出了具体的建议和对策。The planned Xiaonanhai power dam which is located in the rare and endemic fishes nature reserve in the upper reaches of the Yangtze River is the largest project of Chongqing City during the 11th 5-year-plan.Ecological impacts of the Xiaonanhai power dam on the rare and endemic fishes nature reserve in the upper reaches of the Yangtze River were predicted and analyzed.Results show that once the dam is built up,it will seriously alter the hydrological characteristics such as current speed,water temperature,water quality,etc.as well as the structure and function of the 72.5 km river section in the nature reserve,eliminating spawning grounds and habitats of some rare and endemic fishes including Myxocyprinus asiaticus,Coreius guichenoti,Leptobotia elongata,Procypris rabaudi and Rhinogobio ventralis.In order to mitigate the ecological impacts of the dam on the nature reserve,some applicable countermeasures were put forward.
