摘    要:虚拟水是解决水资源短缺和水资源安全的新概念,已成为国际水资源研究的新动向.通过对吉林省48个县(市、区)1998-2010年玉米虚拟水含量的计算,分析和探讨了其时空分异特征.吉林省1998-2010年玉米虚拟水总量呈波动趋势,2010年达最大值.各县(市、区)玉米虚拟水含量差别较大,中部地区玉米虚拟水含量较低,东部和西部地区玉米虚拟水含量较高.梨树县玉米虚拟水含量明显低于其他县(市、区),玉米种植耗水量最小;白城市市辖区玉米虚拟水含量最高,玉米种植耗水量最大.

关 键 词:玉米  虚拟水  时间变化特征  空间分异规律

Abstract:Virtual water was a new concept to solve the water shortage and water security, which was a new trend of international water research in recent years. The maize virtual water of Jilin Province from 1998 to 2010 was calculated to study its spatial- temporal distribution rules. The maize virtual water in Jilin Province presented a fluctuation tendency and reached its peak in 2010. The maize virtual water of the central region was signifi- cantly lower than that of the eastern and western regions. The maize virtual water in the city area of Baieheng City was significantly higher than other counties (cities, districts), and that of Lishu County was the lowest.
Keywords:maize  virtual water  spatial distribution  temporal distribution
