摘要： 本文根据官厅蒸发站20米2蒸发池的观测资料与气象要素特征值之间关系,建立道尔顿类型的水面蒸发计算模式,计算了京津唐地区60个气象站的年、月蒸发值,并绘制年、季(典型月分)的蒸发分布图。

Abstract: According to the observed data of the relation evaporation tank (20m2) and the characteristics of mateorological elements, We obtained a model of evaporation from water surface on the basis of Dalton's Law. E0=0.144(1+0.75U1.5)[D+d(T1.5)(a-1)T1.5](mm/day) According to this model, we estimated annual and monthly evaporation fo 60 meteorological observation stations in the areas and drew an annual and seasonal evaporation map (year, typical months) The examination of the presented formula shows that the monthly maximum relation error of estimation is baout 6%, yearly relation error is about 0.4%.
