摘　　要：[目的]针对新疆白杨河流域存在供需用水矛盾、地下水超采、生态用水量被挤占等问题,对该流域进行水资源优化配置,为新疆白杨河流域经济健康发展及水资源分配提供合理依据。[方法]运用水资源综合评价模型对新疆白杨河流域、达坂城区、托克逊县水资源承载力进行分析,建立以缺水量最小、经济效益最大、公平性最优为目标函数的多目标模型,采用第二代非支配排序算法(NSGA-Ⅱ)对多目标模型求解,获得理论最优配水方案。[结果]新疆白杨河流域综合评价指数为1.0;规划年(2030年)水资源优化配置后,相对于ARIMA模型预测结果和计划配水方案用水量分别减少23.7%和9.9%,而GDP分别增加10.5%和降低1.4%,流域配水公平性由差距悬殊到绝对平均。[结论]新疆白杨河流域水资源目前处于濒临超载和轻度不协调状态;水资源优化配置方案能够实现地区的水资源高效利用及合理配置。[Objective]The conflicts between water supply and demand,overexploitation of groundwater,and ecological water consumption in the Baiyang River basin in Xinjiang Wei Autonomous Region was evaluated,and the water supply areas of the basin were taken as the research objects to optimize the allocation of water resources for the basin in order to provide a reasonable basis for the healthy development of the economy and the allocation of water resources.[Methods]A comprehensive evaluation model of water resources was used to analyze the water resource carrying capacity of the Baiyang River basin,Daban District,and Tuokexun County.Thus,a multi-objective function model providing for the smallest water shortage,the largest economic benefit,and the best fairness was established.A second-generation non-dominated sorting algorithm(NSGA-Ⅱ)was used to solve the problem.Through the optimization of the results,the optimal water distribution plan was obtained.[Results]The comprehensive evaluation index of the Baiyang River basin was 1.0.After the planning year(2030)when the allocation of water resources was optimized,water consumption decreased by 23.7%(compared with the predicted results of the ARIMA model)and 9.9%(compared with the planned water distribution plan),and GDP increased by 10.5%and decreased by 1.4%respectively.The fairness of water distribution in the basin changed from a wide variation to an absolute average.[Conclusion]The water resources of the Baiyang River basin are currently on the verge being overloaded and slightly uncoordinated.Optimal allocation of water resources could produce the efficient use and reasonable allocation of regional water resources.
