摘　　要：QUAL2K是一维稳态水质模型,由美国环保局开发并在QUAL2E模型的基础上发展起来的。采用QUAL2K模型对西苕溪干流梅溪段的水质进行了模拟和预测。针对西苕溪的具体情况,选用COD、氨氮和总磷作为模拟预测指标,用模型率定法并参考相关文献确定了COD降解系数KC、氨氮降解系数KN和总磷平衡系数KP等水质参数,并对模拟结果进行了验证,结果表明预测值和实测值的相关性较好。QUAL2K model is a one dimensional steady water quality model, which was exploited by United State Environmental Protection Bureau and developed on the base of QUAL2E model. Based on the flow characteristics and pollutant distribution of West Shaoxi, QUAL2K model was used to simulate and predict water quality in the Meixi section of the main stream of West Shaoxi,with COD, ammoniac nitrogen and total phosphor as indexes for simulation and prediction. Some important quality parameters, such as COD decay coefficient（ Kc ） , ammoniac nitrogen degeneration coefficient （KN ） and total phosphor balance coefficient （Kp） , were determinated through using the model rating method and referring to related literature. The simulation resuhs were verified and showed that the predicted values fit with the measured ones well.
