摘要: 利用吉林省蒸发量的逐日观测资料,对1998-2001年吉林省非冰冻期(5-9月)小型蒸发皿与E601型蒸发皿的蒸发量观测数据进行对比研究,并利用1951-2015年吉林省小型蒸发皿观测蒸发量数据分析了其变化特征。结果表明:1998-2001年吉林省非冰期(5-9月)平均蒸发量的月变化明显,与E601型蒸发皿相比,小型蒸发皿观测的蒸发量明显偏大,且蒸发量偏大率(D)随月份(5-9月)增加而减小。1951-2015年吉林省年平均蒸发量呈自东南部地区向西北部地区逐渐增加的空间分布特征;春季、夏季、秋季蒸发量的空间分布与年分布特征较相似。近65 a来吉林省年平均蒸发量呈略下降的趋势,但各季节和各地区蒸发量的变化趋势并不完全相同。

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.

Key words: Small evaporation pan, E601 type evaporation pan, Evaporation
