摘　　要：通过新疆昌吉地下水均衡试验场中的不同矿化度EФ20蒸发器水面蒸发试验研究,得出高盐度水面蒸发的一般规律。通过数据对比分析,表明在外部环境条件相同时,高盐度水面蒸发量与矿化度之间呈显著负相关关系,即矿化度越高,水面蒸发越微弱,反之则蒸发越强烈,这主要是由于水体中的盐分子对水分子的吸引力作用造成的。根据实测数据拟合出水面蒸发量与矿化度之间的函数关系,并计算出高盐度水面蒸发折算系数。The general law of the high salinity water surface evaporation was obtained by water surface evaporation experiments of different salinity EФ20evaporator at the Changji Groundwater Balance Test Station, Xinjiang. By comparatively analyzing the data, we found that under the same external environment condition, there is a negative correlation between high salinity water surface evaporation and salinity, that is to say, the higher the salinity, the more weaker water surface evaporation, on the Contrary the more stronger water surface evaporation. This is mainly due to the attraction effect of salt molecules to water molecules in the salt water. According to the experimental data, functional relationship between the water evaporation and the salinity was fitted out, and the conversion coefficient of high salinity water surface evaporation was calculated.
