Base on the daily meteorological observation data from 1971 to 2010 in Jilin Province,the spatial and temporal distribution characteristics were analyzed in the pan evaporation and actual evaporation by using the accumulated anomaly,climate tendency coefficient,climatic trend rate and Gaoqiao formula methods. The results were as follows.The pan evaporation rate decreased significantly from 1971 to 2010,especially in spring.In the other three seasons,the rate showed a weak increasing tendency.In terms of space,the pan evaporation in Jilin Province was decreasing in the eastern part and parts of the central region and increasing in the western part.However,there were certain changes in different seasons.The actual evaporation accounted for 25%of the pan evaporation in Jilin Province with a slight increasing trend over time.Among the many meteorological factors affecting the pan evaporation,the major factors were wind speed and daily temperature difference.The actual evaporation showed the significant response to the precipitation and daily temperature difference,the daily temperature difference was the more significant factor affecting the actual evaporation.
