摘　　要：针对传统计算入湖河口水环境容量采用混合区控制方法存在计算量和误差大的问题,提出一种以遗传算法为基础的湖泊污染源控制方法,基于反问题理念将遗传算法与湖泊二维水质模型相结合,仅需调用一次水量水质模型,即可计算入湖各河口的水环境容量。以太湖为例,构建了基于遗传算法的入湖各河口水环境容量计算模型,计算结果表明该模型简便、效率高,获得了太湖主要入湖各河口的COD水环境容量由大到小的排序规律。Traditional computing the lake estuarine water environmental capacity with mixing zone control method has a large amount of computation and error problem. This paper proposes a genetic algorithm-based method for control of lake pollution. From the view of the inverse problem, a new model is established by combining genetic algorithm and 2D lake water quality model. The new model is used lake 2D model only once to calculate the estuary water environment ca- pacity. Taking Taihu Lake as an example, the estuarine water environmental capacity calculation model is established on the basis of the genetic algorithm. The results show that the model is simple and efficient. Finally, it gets the Taihu I.ake main estuarine＇s COD environmental capacity in descending order.
