摘　　要：根据三峡库区次级河流“回水变动区”的定义,以及云阳县澎溪河河口近年来的水文特征及水质现状,采用狭长湖库移流衰减模型模拟澎溪河河口回水变动区回水时段的水质,确定模型参数K1,计算了2005年污染物浓度值。结果显示:计算值与实测值的相对误差在±4%以内,提示模型可以用来模拟三峡库区次级河流河口回水变动区回水时段的水质。According to the definition of the area of fluctuant backwater, and the information of hydrology and water quality of Peng Xi River in YunYang County, based on long and narrow reservoir attenuated running model to simulate the water quality for the period of time of backwater of Peng Xi River Embouchure, the parameter K1 and the concentration of BOD and COD in water quality on 2005 were computed. The result showed that the relative errors of measured value and computed value were less than ＋4%, it＇s possible that this model could simulate the water quality for the period of time of backwater in the area of fluctuant backwater of Three Gorges Reservoir anabranch - embouchure.
