摘　　要：本文利用全国不同地区13个20 m^(2)或10 m^(2)蒸发池数据,验证广义互补S型公式对小型水体水面蒸发估算的效果,并分析了其参数αHT的变化特征。结果表明,无论采用暖季(4—9月)的数据还是采用全部数据(有蒸发量观测时期的数据),S型公式均能够有效估算大型蒸发池的蒸发量,效果优于采用率定风速函数的Penman公式。利用暖季(4—9月)数据拟合的参数αHT介于1.00~1.92,均值为1.52,与相对湿度和温度具有显著负相关关系,利用相对湿度确定参数αHT的S型公式能够有效估算蒸发池的蒸发量。The performances of the Sigmoid Generalized Complementary(SGC)equation for estimating evaporation from small water bodies were verified by using the data of 13 standard 20 m^(2) or 10 m^(2) evaporation tanks in different regions of China,and a method of determining its unique parameterαHT were proposed.The results show that the SGC equation can effectively estimate the evaporation from the tanks during the whole year and the warm season(April-September),and perform better than the Penman equation with calibrated wind function.The calibratedαHT ranges from 1.00 to 1.92 with a mean value of 1.52,and theαHT is significantly correlated with the relative humidity and air temperature.The parameterαHT can be effectively determined by the relative humidity by using the linear relationship.
