Analysis of Evaporation Results Measured by 20 cm Diameter Evaporator and E601 Evaporator——Hydrological Station in Chongli as an Example

According to evaporation data during the 10 years of 1986-1995 at hydrological stations in Chongli,this paper analyzed meteorological factors affecting evaporation,and compared the differences in the evaporation results between the 20cm diameter evaporator and E601 evaporator.The reason why results measured by 20cm diameter evaporator were larger and,the relationships between the evaporation results measured by the two evaporators were further delineated.
