摘　　要：应用WIN/DYNHYD+和WASP6建立了陈行水库水动力模型和水质模型,并对水质模型中水质参数进行率定和验证;应用建立的陈行水库水质模型研究了陈行水库的自净规律。研究表明,陈行水库的水温、水位、流场、水力停留时间对水库自净作用有很大影响;在水温正常变化范围内,水温越高,水力停留时间越长,陈行水库自净能力就越强,并提出陈行水库运行管理建议。A hydrodynamic model and a water quality model applied to Chenhang Reservoir are established by use of the WIN/DYNHYD+and WASP6 modelling system, and the water quality parameters are calibrated and validated. The water quality model is used to analyze the self-purification mechanism of Chenhang Reservoir. It is concluded that water temperature, water level, flow field, and hydraulic residence time (HRT) have great influences upon the self-purification capacity of Chenhang Reservoir. Within the normal variation range of water temperature, the self-purification capacity is greater in the condition of higher water temperature and longer HRT. Suggestions for the management of Chenhang Reservoir are proposed.
