南水北调西线工程将雅砻江、大渡河和黄河连为一体,形成泛流域水资源系统,涉及确定合理的调水总量、调水规模与布局以及调水量合理分配等关键技术问题。针对该复杂大系统,研究跨流域水资源多维尺度模拟和优化方法,建立了3层结构的泛流域水资源时空优化调配模型系统,将调水区7条河流与黄河受水区67地市统一优化调配。采用大系统协调技术和嵌套遗传算法动态调节机制求解泛流域水资源优化分配问题,提出了一套适宜的调水规模、工程布局及调水量空间合理分配方案,为南水北调西线工程的宏观决策提供科学支撑。
The Western Route Project of South-North Water Diversion will integrate the Yalong River, Dadu River and the Yellow River to form a pan-basin water resource system, which involves key technical issues such as determining the total amount of water diversion, the scale and layout of water diversion, and the rational distribution of water diversion. Aiming at the complex large-scale system, the multi-dimensional scale simulation and optimization methods of water resources across the river basin are studied, and a three-layer model of water resources space-time optimal allocation system is established. The seven rivers in the water diversion area and the 67 cities in the Yellow River water receiving area are unified Optimize deployment. Large-scale system coordination technology and nested genetic algorithm dynamic adjustment mechanism are used to solve the problem of optimal allocation of water resources in the Pan-River Basin. A set of suitable water diversion plan, project layout and rational distribution of water transfer volume are proposed. Provide scientific support.
