建立了秃尾河在不同污染条件下的二维非稳态水流水质模型，基于水量、水质同步实测数据对模型进行了率定验证。运用所建模型对研究区域水流水质过程进行数值模拟，定量分析了研究区域在不同污染条件下的污染混合带长度及对污染源下游水质的影响程度。通过对不同污染条件下秃尾河下游的水质浓度场的计算分析，结果表明：在污水排放控制总量为1．80万t/d、不考虑降解系数的情况下，清水工业园混合带长度为60 m ，距离污染源8000 m断面的水质COD、氨氮、石油类能达到地表水Ⅲ类水标准（ GB3838-2002）；而在污水排放控制总量为1．90万t/d、考虑降解系数的情况下，清水工业园混合带长度为64 m，距离污染源9000 m的断面水质COD、氨氮、石油类能达到地表水Ⅲ类水标准（ GB3838-2002）。通过模型预测水环境是保护水环境的有效方法。

A 2-D unsteady hydrodynamic-water quality model was established for submerged area of Tuweihe in different conditions of pollution, and the simultaneous hydrodynamic and water quality data was used to calibrate and verify the model.The paper used the model to simulate the process of regional water flow and water quality, and quantitatively analyzed the length of pollution mixed band in the study area under different conditions and the impact of pollution on downstream water quality .Through the cal-culation and analysis of concentration field of water quality in downstream of Tuwei River under different conditions, the results showed that the total amount of sewage discharged is 18,000 t /d, without consid-ering the degradation factor, the length of water mixed belt in Qingshui industrial park is 60m, the chem-ical oxygen demand(COD), ammonia nitrogen(NH3-N) and total phosphorus(TP) in the cross section of 8000 m distance from water pollution can reachⅢclass standard of Chinese surface water ( GB3838-2002);while the total amount of sewage discharged is 19,000 t /d, without considering the degradation factor, the length of water mixed belt in Qingshui industrial park is 64m, the chemical oxygen demand ( COD) , ammonia nitrogen( NH3-N) and total phosphorus( TP) in the cross section of 9000 m distance from water pollution can reachⅢclass standard of Chinese surface water ( GB3838-2002) .Forecast of water environment by the model is an effective way to protect water environment.
