摘　　要：对基于多目标遗传算法的水资源优化配置模型进行研究,可为城市水资源可持续利用和规划管理提供一定的参考依据。根据西宁市的水资源实际情况,建立水资源优化配置模型,并利用多目标遗传算法对该区域水资源进行了优化配置。结果表明,在各水平年不同保证率条件下,西宁市水资源经优化配置后的总供水量有所减少,各个水源的供水量亦有不同程度的减少,其中地表水和地下水减少的供水量较为明显。研究结果表明,多目标遗传算法在水资源优化配置中的应用效果较好,优化结果合理可靠。The optimal deployment scheme based on multi-objective genetic algorithm can provide references for urban sustainable utilization and management of water resources.The optimal deployment scheme for Xining City was established according to the actual situation of water resources,and was optimized by using multi-objective genetic algorithm.The results show in different years with various guarantee rates,the supplies of total and individual water resources reduced substantially after optimal deployment,while the reductions in surface water and groundwater were more significant.The application of the multi-objective genetic algorithm in optimizing water resource deployment showed preferable effects,resulting in reasonable and reliable results.
