摘　　要：针对流域水资源系统中以“面”为主的多水源配置和以“线-点”为主的水库群调度耦合问题,提出多水源配置与水库群优化调度相耦合的二层结构方法。以永定河流域为研究实例,提出包括供水规则、引水规则、多水源供水策略以及共同供水任务分配策略的多水源配置与调度规则,以此建立多水源配置与水库群优化调度模型,分析多水源供水和不同需水情景下的调度方案,以及最优方案下的供水效益。结果表明:永定河流域考虑本地水、引黄水、南水北调水和再生水的多水源供水与节水相结合的情景方案为最优方案,生活用水保证率均大于99%,工业用水保证率均大于97%,灌溉分区供水保证率为76.7%~90.2%(除桑干河上游外),三家店断面生态供水保证率为96.3%;通过多水源供水和节水策略,可以极大地改善用水户的供水效益和保障三家店断面生态水量需求。本文方法可为流域多水源配置与水库群优化调度研究提供借鉴。In this paper,a two-tier structure method is proposed for the coupling of multiple water sources allocation at the“plane”level with the optimal operation of the reservoir group at the“line-point”level for the river basins.Taking Yongding River basin for example,the rules of multi-sources-based water allocation and operation,including the rules for water supply and water diversion,multi-source water supply strategy and common water supply task allocation strategy are formulated,the model for multiple water sources allocation and optimal operation of reservoir group is established,and the operation schemes under the various scenarios of multi-source water supply and water demand in the basin as well as the water supply benefits from the optimal scheme are analyzed.The results show that:①In the Yongding River basin,the scenario of combining multi-source water supply system consisting of the local water,water diverted from Yellow River,water from the South-to-North Water Diversion Project and the reclaimed water,with the water conservation is the optimal scheme.②The guarantee rate of domestic water supply,industrial water supply and ecological water in Sanjiadian Section is greater than 99%,97%and 96%respectively,with the guarantee rate of water supply in irrigation zones ranging between 76.7%—90.2%(except the upper reaches of Sanggan River).③The adoption of multi-source water supply and water conservation strategy can lead to significant improvement of the water supply efficiency for water users and abundance of the ecological water volume of Sanjiadian Section.The method described herein can serve as references for the study on the allocation of multiple water sources and the optimal operation of reservoir groups in a given river basin.
