摘　　要：针对南水北调东线工程江苏段受水区的水资源调度与配置问题,以受水区总缺水量最小和泵站总能耗最小为目标,建立南水北调东线工程江苏段水资源优化调度模型。将南水北调工程调水与本地水资源进行联合配置,并以经济效益、社会效益、环境效益最大为目标,构建南水北调东线工程江苏段水资源配置模型。采用基本方案和节水方案进行了模型模拟,结果表明,在降水保证率分别为50%、75%和95%3种情况下,受水区节水方案缺水率比基本方案分别下降了2.91%、3.61%和3.83%;受水区节水方案下各工程基本完成了受水区的供水任务,且优先利用了泵站单位能耗较小的运西线进行调水,说明优化调度配置方式在保障受水区用水的基础上,能够以更为经济节能的方式运行。Aiming at the water resource dispatching and allocation problem in the receiving area of the Jiangsu Section of the East Route Project of the South-to-North Water Diversion Project,with the goal of minimizing the total water shortage in the receiving area and the total energy consumption of the pumping station,a water resource optimization scheduling model of the Jiangsu Section of the East Route Project of the South-to-North Water Diversion Project was established.The transfer water from the South-to-North Water Transfer Project was jointly allocated with local water resources,and the water resources allocation model for the Jiangsu Section of the East Route Project of the South-to-North Water Diversion Project was constructed with the goal of maximizing economic,social,and environmental benefits.The model simulation was conducted using the basic scheme and water-saving scheme and the results show that under the three conditions of 50%,75%,and 95%precipitation guaranteed rates,the water shortage rate of the water-saving scheme in the receiving area decreased by 2.91%,3.61%,and 3.83%compared to the basic scheme,respectively.Under the water-saving scheme in receiving area,each project has basically completed the water supply task in the receiving area,and prioritized the use of the Yunxi Line,which has a lower unit energy consumption of the pumping station,for water transfer.This indicates that the optimized dispatching and allocation model can operate in a more economical and energy-saving way while ensuring water use in the receiving area.
