摘　　要：该文应用美国三维水环境流体动力学模型(简称EFDC模型)对特大型水库进行了水流水温数值耦合预测计算,深入研究了水库的水热循环规律,并对分层型水库的水位、流速和水温分布规律进行剖析。在梯级水电站联合运行环境下,重点分析了高坝大库水温分层规律,探讨了建库前后的水温变化规律和梯级水库建设的累积影响,为调整梯级水电规划方案提供科学决策依据。In this paper, the United States Three-Dimensional Fluid Dynamics Code Model of the water environment （EFDC HYDRO） coupled numerical calculation of water temperature on large reservoirs. Depth study of the laws of thermal cycling of water in Reservoir and stratification of the water reservoir and flow rate. Joint operation of cascade hydropower stations in the environment, the focus of an analysis of high dams and large reservoirs of water temperature stratified law. Joint operation of cascade hydropower stations in the environment, the focus of an analysis of high dams and large reservoirs of water temperature stratified law, and steps of the cumulative effects of reservoir eonstr.The changes of water temperature is studied before and after dam construction, for adjustment of the cascade hydropower planning programs to provide scientific basis for decision making.
