摘要: 吉林省中部是中国重要的商品粮生产基地,尤以玉米的高产稳产而闻名。探讨不同降水年型下吉林省中部玉米生长期的耗水特征及玉米生产水足迹的空间分异,对实现农业水资源的合理利用,促进农业的稳定持续发展具有现实意义。结果表明:研究区北部县(市)的玉米生产水足迹较高,而南部县(市)的玉米生产水足迹较低。枯水年玉米生产水足迹最大,丰水年最小。玉米生产水足迹以绿水足迹为主,约占75%。绿水足迹以有效降水足迹为主,丰水年有效降水占绿水足迹的比例最大。玉米生长期土壤水消耗量以枯水年最大,丰水年最小。

Abstract: The middle of Jilin province is an important production base of commodity grain in China, and is famous for its high and steady maize yield. In the present study, the characteristic of water consumption and the spatial variations of the water footprint of maize growth were analyzed, which was beneficial for the rational utilization of agricultural water resources and the sustainable development of agriculture. It was shown that the water footprint of maize production was higher in the north of study area, and was lower in the south. The footprint in the drought year was the largest, yet the footprint in the humid year was the smallest. The major proportion of water footprint was the green water footprint, which was almost 75%. The green water footprint was dominated by the effective precipitation footprint, of which the largest proportion was recorded in the humid year, and the smallest proportion was recorded in the drought year. The consumption of soil water was the largest in the drought year, and the smallest in the humid year.

Key words: water footprint, maize, rainfall years
