从水文角度讨论了蒸发悖论问题,以五道沟水文水资源实验站的实测资料为例,进行了剖析。成因上讲,水面蒸发不仅与气温有关,还与降水、湿度等因素有关。实例表明,将水面蒸发与气温直接相关,发现水面蒸发与气温几乎无关,而与大气中的湿度关系密切。因而蒸发悖论的说法,有待更多资料的分析与验证。 From the hydrological point of view, the evaporative paradox is discussed. Taking the measured data of Wudaogou Hydrology and Water Resources Experimental Station as an example, the analysis is carried out. Genesis, water evaporation is not only related to temperature, but also with precipitation, humidity and other factors. The examples show that the water surface evaporation is directly related to the temperature, and it is found that the water surface evaporation has little to do with the temperature, but closely related with the atmospheric humidity. Therefore, the paradox of evaporation argument, pending more data analysis and verification.
