Abstract  Based on the principle of thermal expansion and contraction,this paper calculates the water level corresponding to different water temperature.The compensation of evaporation data for the change of water volume is studied,and a compensating mathematical equation closer to the real evaporation situation is obtained,which can get more accurate evaporation data.According to study and analyze the data of April,August and December in 2017,the correlation and impact factors between measured evaporation and water temperature,water level at 4℃,and the difference between measured evaporation and corrected evaporation are obtained.
Key wordsmeasured evaporation      corrected evaporation      water temperature      water level
