河北省南水北调中线受水区水资源统一调配方案研究

针对南水北调中线受水区外调水及当地地表水来水过程的不均匀性及来水频率的不确定性、供用水系统的复 杂性( 多水源、多工程、多用户) 等特点, 以河北省南水北调受水区为研究对象, 以多目标群决策理论和大系统分解协 调理论为指导, 以优化与模拟为主要技术, 构建了基于 MIKE BASIN 的 1+ 7 受水区水资源优化调配模型, 制定了 基于不同年份、不同保证率、不同节水水平、不同用水户需求条件的受水区水资源优化调配方案。在 2020 年供受水 区来水频率组合( 引江水 P = 50% 、当地地表水 P = 50%) 条件下, 对基本节水及高效节水的优化调配方案优化效果 进行了分析, 以期在充分利用水资源、满足需水要求的情况下, 寻求多水源与多用户之间最优的配水方案, 实现区域 综合效益最大化, 促进区域经济可持续发展。 Tar geting the inhomog eneity of inflow pr ocess and uncertainty o f inflow fr equency o f transferred water and lo cal sur2 face w ater in the w ater r eceiv ing area of the Middle Route of the So uth2to2 No rth Water Tr ansfer Project as w ell as the complex2 ity of the wat er supply system ( multi2sour ce, multi2pro ject, multi2user) , we selected a w ater receiv ing area of t he South2t o2North Water Tr ansfer Pr oject in H ebei prov ince as the r esear ch object.
