| 摘 要： | 从表面看,影响水面蒸发量的气象因素有日均气温、日最高气温、日最低气温和日均风速及日均相对湿度。通径分析表明,平均气温是水面蒸发量的主要的影响因素,其它气象因素大多通过平均气温对水面蒸发量起作用。与此同时,本文根据影响水面蒸发量的最主要因素,建立了相应的多元回归模型。结果表明,该模型具有较高精度和良好可靠性。

| Abstract: | This paper discusses seven Climatic factors that affect water surface evaporation.Simple correlation analysis indicated that five factors,inCluding average air temperature 、maximum air temperature、minimum air temperature、wind velocity and the relative humidity,have remarkable correlation with water surface evaporation.However,path analysis indicated that only the average air temperature was the key Climatic factor to water surface evaporation.The other six Climatic factors mostly indirectly affected water surface evaporation through air temperature.Meanwhile,we establish multivariate regression function based on Climatic factors which affect water surface evaporation largely.It shows that the function has sound reliability and very good accuracy. |
