摘　　要：提出了单座水库与单座补水泵站水资源优化调度的非线性数学模型,模型以年内各时段的缺(弃)水量的平方最小为目标函数,各时段水库供水量和泵站引提水量为决策变量,各时段水库库容为状态变量,以年调节水库可供水量、泵站年引提水总量、水库与补水泵站的联合运行准则(泵站闲时补库、忙时供水)等为约束条件,并以南水北调东线一期江苏境内"骆马湖-皂河站"为实例,采用动态规划逐次逼近法进行求解。结果表明,相同供水保证率时,50%、75%、95%来水频率下泵站补水量、缺水量、弃水量比常规调度均有减少。An optimal operation model for＂single reservoir-single pump station＂system was constructed by taking the minimum volume of squares of water shortage（surplus water）in each period as the objective function,the water supply of reservoir and the water volume to be pumped as the decision variable,the reservoir storage capacity as the state variable,annual total water supply of reservoir and pump station as the constraint,in addition,the combined operation rule of reservoir and pump station was also considered as the constraint.The Luoma Lake-Zaohe pump station section of South-to-North Water Diversion Project was taken as a study case,which was solved by means of DPSA.The results showed that the water volume to be pumped all decreased compared with regular schedule as well as the water shortage and the discarded water in the same water-supply guaranteed rate of 50%,75% and 95% hydrological year.
