摘　　要：针对共同承担下游防洪任务的梯级水库,建立了基于库容补偿的梯级水库汛限水位动态控制域计算方法;分别建立了上、下库有富余防洪库容情形下的防洪库容置换模型,并从防洪有利和蓄水有利角度建立了改变上库出库过程的调度策略;以滹沱河岗南-黄壁庄梯级水库为例,建立了有富余防洪库容的水库水位与关联库汛限水位抬升值之间的关系,取得了合理的结果。A method is described for estimation of the dynamic control bounds of flood limited water level in cascade reservoirs that share responsibility of flood control, based on an analysis of their storage compensation mechanism. Flood storage compensation models are developed for two cases of abundant flood-control storage available in the upper reservoir and lower reservoir, and corresponding operation rules are drawn for the upper reservoir with consideration of differences in safety and benefits. Application to the case of Gangnan and Huangbizhuang cascade reservoirs shows reasonable results, including a relationship of water level in the reservoir with abundant storage versus the exceeding range of flood limited water level raised in the related reservoir.
