| 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%. |
