开展水量水质双控约束下水资源优化配置研究是落实新时期“节水优先”方针、保障区域水安全和促进水资源可持续利用的基础支撑。针对我国北方地区资源型缺水、工程型缺水并存的问题，以山东省昌乐县为例，结合WEAP模型与传统水资源配置理论方法，根据区域用水需求与总量控制及水功能区限制纳污管控要求，统筹协调生活、生产、生态用水，建立基于水量水质双控的区域水资源优化配置模型，采用AHP法、熵权法、AHP-熵权耦合法计算不同情景方案的配置效益并优选配置方案。结果表明：规划水平年农业、城市供水保证率分别为50%、95%时，基于用水总量控制的跨流域调水、强化行业节水和水污染治理以及加大再生水回用相结合的配置方案（B4方案）综合效益最大，各行业用水需求均能得到满足，GDP较现状水平年增加709.01亿元，再生水利用率提高至25%。

Research on the optimal allocation of water resources under the control of water quality and quantity provides a foundation for new-era guidelines of “Giving Priority to saving water” and ensuring regional water security and promoting sustainable use of water resources. With regard to the coexisting water shortage in both resources and engineering patterns in North China, Changle County was taken as a case study and quantity/quality-dual-control-based models for optimal regional allocation of water resources were established by combining a WEAP model with conventional theory and methods for allocation of water resources, according to regional water demand, total quantity control, and pollution control requirements in water functional zones, to coordinate domestic, production, and ecological water usage. Implying AHP, entropy weight method and AHP- entropy weight coupling method, the allocation benefits of plans under different contexts are examined, and the best allocation plan is selected. Results show that in the study sites in the future planning year, when the guarantee rate of water supply is 50% and 95% respectively for irrigation and urban, the scenario B4 combining the water resource development based on controlling total water consumption, strengthening water-saving practices in industries, water pollution control, and reusing more reclaimed water, achieves the greatest comprehensive benefits. Compared to the current year, the water demand of all sectors can be met, the annual GDP increases by 70.901 billion yuan and the utilization rate of the reclaimed wastewater accounts to 25%.
