摘要: 引言蒸发是水分化汽的过程。空中水汽的来源,是借洋面上及陆地上的水分蒸发所供给。每年洋面上蒸发量为114厘米,折合水量为411,600立方公里。全部陆地上水体与地面的蒸发量为54厘米,折合水量为63,000立方公里。这些水量在空中形成降水,返回大地,因此蒸发过程是水文循环的重要环节。

Abstract: An experimental research of evaporation from water surfaces has begun in China since 1956.The data of 19 experimental stations over the country have been collected and processed.On the basis of the available data some evaporation models have been developed. In accordance with data of 13 stations,including Kwangchow station,Chongking station etc,we have set up three evaporation models for humid regions of China and from the other 6 stations,we set up three evaporation models for arid regions.A verification indicates that model with curvilineal climatic index seems to be better than the linear model and the goodness of the mass transfer model is the least. In comparison with the Soviet and the American well-known model,it shows that the developed models are more suitable for China.
