摘　　要：通过对吉林省玉米生长过程水足迹的计算,探讨了不同降水年型玉米生长过程水足迹及其水分来源的变化规律,并利用ArcGIS软件对吉林省玉米生长过程水足迹空间差异进行了分析。结果表明,吉林省玉米生长过程水足迹以绿水足迹为主,占50%左右;对比不同降水年型玉米生长过程水足迹,枯水年最高,平水年次之,丰水年最低;玉米生长过程水足迹空间差异明显,中部地区玉米生长过程水足迹最高,其次是西部地区,东部地区最低。Based on the concept and calculation methods of water footprint, this paper estimated the water footprint of maize production in differ- ent precipitation years and discussed the changes of water source. This study investigated the spatial differences of water footprint for maize production in Jilin Province by using ArcGIS software. The results indicated that：OThe major portion of water footprint of maize production was green water, which accounted for 50% or so. （2）Comparing water footprint of maize production in different precipitation years, it was highest in the dry year, the normal year took second place and lowest in the wet year. （3） The spatial difference of water footprint for maize production was obvious, which was highest in the middle region, moderate in the west region and lowest in the east region.
