摘　　要：以引大济湟调水总干渠工程运行后河流水文情势的变化,分析工程建设导致的主要生态环境影响,并相应提出优化工程运行方式、建设生态放水设施、过鱼道等生态环境影响保护措施,尽量减缓对区域生态环境的破坏。分析表明,在采取严格环境保护措施的前提下,工程运行后引水枢纽的下泄水量可满足大通河生态水量要求,对区域生态完整性影响不大,可维持一定种群和资源量,从生态环境角度论证该工程建设方案可行。Based on the hydrological situation change after the operation of the water diversion from the Datong River to the Huangshui River,the influence of the project on the ecological environment was analyzed.Some ecological environmental protection measures,including optimizing the operation mode,constructing ecological drainage facilities,and building fishways,are put forward.Analysis shows that,under the premise of taking strict environmental protection measures,the discharge flow of the diversion system can satisfy the eco-environmental water demand of the Datong River after the project is put into operation.The project has little effect on the ecosystem integrity and can maintain the number of species and resources.The water diversion project construction scheme is feasible from the perspective of the ecological environment.
