Aiming at the total 1 billion cubic meter flood control capacity allocation problem of Qingjiang cascade reservoirs,based on the control conditions and flood control scheduling of Qingjiang cascade reservoirs,seven feasible flood control capacity allocation schemes were present.Then the flood control effects of Qingjiang cascade reservoir that serves as a complement to Three Gorges reservoirs to Jingjiang River Reach as well as the power generation benefits of Qingjiang cascade power stations based on long series of runoff data were analyzed.The research results showed that compared with the original allocation scheme,on the premise of ensuring the safety of upstream and downstream flood control,it was recommended to reserve more flood control storage capacity to the downstream Geheyan Reservoir with the better effect of flood control and power generation.The research conclu-sions can provide decision-making reference for the scientific application of flood control capacity in actual operation of Qingjiang Cascade Reservoir.
