针对影响水库水温模拟效果的常见问题,提出以水温-气温相关法确定缺乏资料地区的现状水温,对水库地形校正效果开展定量分析,讨论了气温直减率对水气界面长波辐射、蒸发、传导的影响程度,对比了部分气象经验公式的热通量计算差异,以二维模型为例定性分析了零方程与双方程紊流模式、静水压力假定与完整垂向动量方程的差异,提出了可通过热量收支平衡、逐月径流量与库容关系等方法定量检验模拟结果的合理性。

英文摘要：

Concerning the common problems affecting prediction results of reservoir water temperature,the method for the determination of natural water temperature in ungauged basins was put forward based on water-air temperature correlation and quantitative analysis for reservoir topographic correction was conducted. The impact of air temperature lapse rate on long-wave radiation, evaporation and conduction across water-air interface was discussed. The difference of heat flux calculated by some empirical meteorological formulas was compared. Qualitative analysis was conducted by comparing the zero equation turbulence model and double equation turbulence model,as well as investigating the difference between the hydrostatic symposium and complete z-momentum equation. A method for quantitative rationality verification of simulation results was put forward through the analysis on heat balance and correlation between reservoir capacity and monthly runoff.
