摘　　要：以金沙江中游某河段为例,通过分析城市河流的特性,建立平面二维水质模型,根据河段内当前存在的排污口的排污特征及其位置分布,计算了多排污口同时排污情况下河段内的水质情况,采用高精度网格对21 km的河段进行计算,模拟了污染物在河流中叠加耦合后的污染带分布,并根据计算结果分析判断污染物是否会对河段中取水口产生较大的影响,从而为城市规划提供了一定的科学依据.Through analyzing the characteristics of an urban river reach in Middle Jinsha River, a two-dimensional water quality model is established to compute the water quality under condition that multiple sewage outfalls discharging at the same time. The pollution zone distribution is simulated under a coupled pollutant superposition condition by using high precision mesh in a 21 km river reach; and analysis is made to find whether the pollutant will have great influence on the water intakes in the reach, and so as to provide scientific data for city planning.
