摘　　要：依据连续性方程、动量方程、自由表面方程、状态方程和水质输运方程,采用有限差分法,建立河道垂向二维水动力水质模型。根据2000-2001年第6次引黄数据资料对水质模型进行调试,建立引黄济津调水工程水质模型。利用已建立的模型,对2002-2003年第7次引黄河道水质进行了预测,并将预测结果与实测数据进行比较,预测结果与实测结果基本一致,表明该模型能较好地预测引黄济津河道水质状况。同时,根据污染物浓度峰值的变化情况,分析了污染物的输移扩散及降解转化规律。Based on continuity equation, momentum equation, free water surface equation, equation for state and water quality transport equation, a 2-D hydrodynamic and water quality model in vertical was established, in which these equations are solved with finite difference method. The water quality model for water supply from Yellow River to Tianjin was established based on the data of the sixth water supply from Yellow River to Tianjin（2000-2001）. The water quality of river from Yellow River to Tianjin was predicted by the model, and the results predicted were compared with the measured data of the seventh water supply from Yellow River to Tianjin（2002-2003）. The comparison shows that the model works well for predicting the water quality status. The law of transport, diffusion and decay of the pollutant was analyzed according to the variation of peak value of the concentration of the pollutant.
