CE-QUAL-W2模型是近年来新开发的水动力学与水质模型,可模拟河流、湖泊、水库等不同条件下多种污染物的迁移转化规律.根据官厅水库狭长、水浅和水文、水力、水质扩散等特点,采用CE-QUAL-W2模型模拟其水质变化,并对模拟模型水质参数进行验证,将其用于官厅水库水质的预测研究;进而提出官厅水库水污染控制的对策及建议.%CE-QUAL-W2 model is a water dynamic and quality model developed recently, which can stimulate removal and transformation rules of several pollutants under different conditions of river, lake and reservoir etc. According to the characteristics of Guanting Reservoir as being long, narrow and shallow, and those of hydrologic、hydrodynamic and water quality diffusion, CE-QUAL-W2 model is used to stimulate the water quality transformation; and the water quality parameters of the model are tested and verified. The model is then used to study the water quality prediction of the reservoir; and countermeasures and proposals to control the water quality of the reservoir are suggested.
