摘　　要：该文以深圳市城市供水系统中的公明供水调蓄工程为例,对区域水资源的合理配置和高效利用展开研究。工程中公明水库被用作城市供水的储备水源,以防止连续枯水年份或发生水污染等严重事件对城市供水构成的巨大威胁。为此,充分考虑调蓄工程的供水运行特点,将调蓄工程中的水库群聚合为"虚拟水库",并建立调蓄工程的引水与供水调度模型;调度模型以引水量最小和公明水库换水量最大为目标函数,采用多目标遗传算法NSGA-II对引水与供水调度模型进行优化求解。在此基础上,采用模糊优选方法在Pareto优化解集空间中寻找满意解,并选择3个代表解对调蓄工程的供水进行模拟。对比与分析模拟计算结果,表明优化调度模型能够高效利用外流域引水资源和提高公明水库的水量交换。Reservoirs optimal operation can improve the efficiency of water allocation and supply. Gongming water supply project is taken as an example, which is subsystem of Shenzhen urban water supply. The project constituted by hybrid reservoirs,including Gongming reservoir, Qiankeng reservoir, Ejing reservoir and Shiyan reservoir. In this project,Gongming reservoir is used to prevent continuous dry years or serious water pollution incidents, which might take great threat to urban water supply. Thus, the storage water of Gongming reservoir is taken as reserved water source for Shenzhen city water supply. For this special task, the Gongming reservoir need keeping at a relatively high water storage level for a long time, and the reservoir requires a certain amount of exchange water to maintain water quality health. The water supply benefit of the hybrid reservoirs and the amount of exchange water of Gongming reservoir are the key objectives. To study the optimal operation of Gongming water supply project for inter-basin water diversion and water supply operating, firstly,aggregation method is applied to aggregate the reservoirs into a＂virtual reservoir＂, which is used for simplifying topological structure of hybrid reservoirs. The dead storage and usable storage of ＂virtual reservoir＂is formed by superposing the dead storage and usable storage of hybrid reservoirs respectively. Then based on ＂virtual reservoir＂, the hybrid reservoirs operation rules for water diversion and water supply are established. Further, the multi-objectives genetic algorithm NSGAII is applied to optimize the operation rules, and the multi-objectives of the operation are the minimum amount of diversion water and the maximum amount of supply water. The water supply operation rule curves divide the storage of＂virtual reservoir＂into 3 functional areas, which are normal water supply area, reduced water supply area and reserved water supply area. When total water storage of＂virtual reservoir＂keeps during normal water supply area, the
