摘　　要：根据潮汐河流的水动力及污染物输运特点,采用二维非稳态水动力、水质模型构造污染源控制反问题,在确保控制点水质达标的前提下,通过对污染源进行反演控制,实现总负荷量最大与污染负荷最优分配的目标。以长江小河口—十二圩段为例,对反演方法进行验证。结果表明,反问题计算结果是可信的。Considering characteristics of water dynamics and pollutants traveling in a tidal river, an inverse problem of water pollution source control was established on the basis of two-dimensional unsteady hydrodynamics and a water quality model. On the condition that the water quality meets the standards at the control points, the maximization of total discharged pollutant loads and the optimal distribution of pollutant loads can be realized simultaneously by inverse control of water pollution sources. The reach of the Yangtze River from Xiaohekou to Shierwei was taken as an example to validate the method.
