摘　　要：提出考虑暴雨径流的生态环境非点源污染负荷定量控制模型。根据污染源的正向指标对非点源污染负荷削减空间进行优化分配,建立污染负荷控制目标模型,采用遗传算法对模型求解,得到最优污染负荷定量控制方案。以柴达木盆地东区都兰县为试验对象,对所提方法的控制性能进行测试。污染负荷控制前和控制后的对比实验结果表明:污染物平均浓度由0.035 mg/L下降至0.012 mg/L,平均削减率65.7%;峰值浓度由0.078 mg/L下降至0.018 mg/L,最大削减率88.2%。研究成果可为柴达木盆地水资源高效利用、水生态保护以及区域水资源规划利用提供理论依据,为区域生态环境治理工程提供数据支撑。A quantitative control model of ecological environment non-point source pollution load considering storm runoff was proposed.According to the positive index of pollution source,the pollution load reduction space of non-point source was optimized,the pollution load control target model was established,and the optimal pollution load quantitative control scheme was obtained by using genetic algorithm.Taking Dulan area of eastern Qaidam Basin as a case,the control performance of the proposed method was tested.The comparative experiment results before and after pollution load control show:The average concentration of pollutants decreases from 0.035 mg/L to 0.012 mg/L,and the average reduction rate reaches 65.7%;The peak concentration decreases from 0.078 mg/L to 0.018 mg/L,and the maximum reduction rate reaches 88.2%.The results could provide theoretical basis for the efficient utilization of water resources,water ecological protection and regional water resources planning and utilization in Qaidam Basin,and data support for the ecological environment management project in this region.
