针对传统集中式多目标优化范式未充分考虑多利益相关主体博弈关系对水库调度决策的影响，导致难以保障河道生态流量的现实问题，设置了共同保障和单独保障两种生态流量保障情景，构建了发电服从防洪调度原则下的梯级水库主从博弈优化调度模型，并在拉萨河流域旁多-直孔梯级水库开展了实例研究。结果表明:梯级水库在共同保障生态流量下综合效益最优，仅由直孔水库单独保障生态流量造成调度效益难以凸显，其中防洪效益降低4。35％，整体发电效益降低1。66％;效益降低的主要原因在于单库保障模式下枯水期旁多水库倾向于蓄水而减少下泄，导致直孔水库过度下降水位来保障生态流量。
Research on leader-follower game optimal operation of cascade reservoirs considering ecological flow
In response to the practical problem of insufficient consideration of the impact of multi stakeholder game relationships on reservoir operation decisions in the traditional centralized multi-objective optimization paradigm,which makes it difficult to guarantee the ecological flow of rivers,two scenarios of joint guarantee and individual guarantee ecological flow were set up.A leader-follower game optimal operation model for cascade reservoirs under the principle of power generation obeying flood control scheduling was established,and a case study was conducted on Pangduo-Zhikong cascade reservoirs in the Lhasa River Basin.The results indicate that cascade reservoirs have the optimal comprehensive benefits under the joint guarantee of ecological flow.It is difficult to highlight the operation benefits under the ecological flow guaranteed by the Zhikong Reservoir alone,in which the flood control benefits are reduced by 4.35％,and the power generation benefits are reduced by 1.66％.The main reason for the decrease in benefits is that under the single reservoir guarantee mode,the Pangduo Reservoir tends to retain water and reduce discharge during the dry season,which leads to the excessive decline in the water level of the Zhikong Reservoir to ensure the ecological flow.
