以米易县为例，针对县域最严格水资源总量控制和自然-社会水循环系统特点，采用总体缺水率最小和分区空间均衡为目标函数，总量控制、供水能力、分质供水等为约束条件，构建了分区独立供水和库群联调的通用水资源调度与配置（GWAS）模型，并采用改进时间-空间两层精英策略的非支配遗传算法， 求解空间均衡调度方案。研究表明，空间均衡调节和强节水约束显著影响各用水单元的分配机制；对比水库分区独立供水与库群联调两种方案的水量配置， 分区供水缺水率最大是白坡彝族乡，库群联调中各乡镇缺水率大幅减少，缺水差异更小。库群联调水资源调配公平性较好，空间上各单元间的缺水率差异较小，基本实现在动态变化下的区域水资源供需平衡。
Taking Miyi County as an example, in view of the most stringent total water resources control and the characteristics of the natural-social water cycle system in the county, a general water resources dispatching and allocation (GWAS) model for independent water supply and reservoir group joint dispatching in different regions is constructed by taking the minimum overall water shortage rate and the regional spatial balance as the objective functions, and the total amount control, water supply capacity, and quality water supply as the constraints, and using the non-dominant genetic algorithm to improve the time-space two-level elite strategy, Solve the space balanced scheduling scheme. The research shows that spatial equilibrium regulation and strong water-saving constraints significantly affect the allocation mechanism of each water use unit; Compared with the water allocation of the two schemes of independent water supply and joint regulation of reservoir groups, the largest water shortage rate of water supply in the district is Bai Po Yi Township, and the water shortage rate of each township in the joint regulation of reservoir groups is significantly reduced, with a smaller difference in water shortage. The allocation of water resources in reservoir group joint transfer is fair, and the difference of water shortage rate between units in space is small, basically realizing the balance of regional water resources supply and demand under dynamic changes.
