Impact Analysis of Artificial Flood Peak Operation on the Comprehensive Benefits of Cascade Reservoirs in the Lower Jinsha River
From May to June,the ecological operation of artificial flood peak is an important solution to promote the natural repro-duction of drift spawning fish in the lower Jinsha River.The purpose of this paper is to explore the impact of ecological opera-tion on the benefits of cascade reservoirs.The dispatching schemes were proposed based on the time periods of ecological opera-tion.Take power generation,water spillage and water supply guarantee rate as indexes,ecological operation schemes were evalu-ated 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.
