干旱区平原水库模拟蒸发量试验研究
Experimental research of evaporation simulation of reservoirs in arid plain area
摘要
Abstract
The surface evaporation of reservoirs in arid plain contributes great to the water losses of the reservoir. The meas-ured evaporation by using the conventional evaporation pan is not in line with the actual evaporation characteristics of the reser-voirs due to large water surface. Therefore, a small area evaporation test was conducted. The evaporation of the pond was meas-ured through water level marking pin, and was compared with the pan evaporation. The results show that in actual evaporation, the evaporation of the pond fluctuates;the evaporation pan has a 9. 1% quicker evaporation speed than the surface evaporation, and the ratio of pan evaporation to the water surface evaporation increases at first and drops then;evaporation in pond is mainly affected by temperature, net radiation, wind speed and saturation vapor pressure difference. Since the water capacity of evapora-tion pan is small, the water heat capacity is smaller compared with the evaporation pond, the heat exchanges with the atmosphere more quickly, so it is influenced by the net radiation and diurnal temperature range greatly.关键词
