Abstract: In this paper,the daily E601 and small pan evaporation observations,during the non-freezing period (from May to September) from the national base meteorological stations in Jilin province from 1998 to 2001,were compared.Besides,the evaporation characteristics of the small pan were investigated.Results indicate that the monthly change of averaged evaporation from 1998 to 2001 in Jilin province is significant during the non-freezing period.The evaporation of the small pan in each site is obviously larger than that of the E601 pan,and the gap between two observations decreases in the order from May to September.The annual mean evaporation in Jilin province gradually increases from the southeast to the northwest during 1951 to 2015.The spatial distributions of evaporation in spring,summer and autumn are similar to the annual situation,while that in winter is slightly different from other seasons.In recent 65 years,the annual mean evaporation in Jilin province shows a decreasing slightly trend,but the trends are different among regions and seasons.
