摘　　要：5~6月的人造洪峰生态调度是促进金沙江下游产漂流性卵鱼类繁殖的重要手段。为探究人造洪峰生态调度对梯级水库综合效益的影响,拟定了梯级水库不同开展时段的生态调度方案,以发电量、弃水量、供水保障率为评价指标,选取丰(25%)、平(50%)、枯(75%)典型来水对各方案进行效益分析。结果表明:典型来水条件下,向家坝在不同时段开展生态调度对梯级水库效益无明显影响,白鹤滩、乌东德分别在6月上旬、6月中旬开展生态调度时梯级水库效益最大。From May to June,the ecological operation of artificial flood peak is an important solution to promote the natural reproduction of drift spawning fish in the lower Jinsha River.The purpose of this paper is to explore the impact of ecological operation on the benefits of cascade reservoirs.The dispatching schemes were proposed based on the time periods of ecological operation.Take power generation,water spillage and water supply guarantee rate as indexes,ecological operation schemes were evaluated under typical high,normal and low flow year conditions with frequencies of 25%,50%,and 75%.The results revealed the following.Considering various inflow conditions,the ecological operation period of Xiangjiaba have no significant impact on the benefits of cascade reservoirs.To maximize the benefits of cascade reservoirs,It is recommended that Baihetan and Wudongde implement ecological regulation in early June and mid June respectively.
