According to the characters of the Miyun reservoir located in northeast Beijing, one dimensional method is used to establish the mathematical model of temperature for the reservoir. In this model the heat exchange between water surface and atmosphere, effective diffusion, inflows, outflows, and thermal advection are considered comprehensively. The effective diffusion coefficient, decay coefficient of short wave in water, etc. are calibrated based on the observed stratification data of 1991 in the reservoir. The mathematical model is verified well with the data of 1992. This model can be used to predict the temperature distribution along the vertical direction for the Miyun reservoir and other similar reservoir.
