摘　　要：论文阐述了河道及水库水温预测对工程建设及生态环境保护的作用。通过介绍河道及水库水温的计算模型,对各种水温模型的适用性及优缺点进行了评述。对于应用立面二维水温模型和三维水温模型,指出应注意紊流模型选取、自由水面模拟方法和网格划分等问题。Water temperature prediction for reservoirs and river channels is very important for hydropower construction and environmental protection. The models of water temperature prediction for reservoirs and river channels were introduced and compared,and the advantages and disadvantages were analyzed in this paper. It also put forward that the issues including the selection of turbulent model,free surface simulation method and computational grid should be noted when using the vertical two-dimensional model and three-dimensional model.
