摘要
虚拟水战略是现阶段水资源研究领域的新思路。以虚拟水理论为指导,计算分析河南省2008年主要农作物的虚拟水含量。结果显示:农作物产品的虚拟水总含量不仅与单位产品的虚拟水含量有关,还与作物的总产量有关;不同地区、不同农产品虚拟水含量之间存在着空间差异性,同一作物虚拟水含量空间差异性也较为明显。从而为河南省调整农业种植结构,提高河南省农业竞争力,以虚拟水战略缓解区域性用水紧张提供新的思路和方法。
At present,virtual water strategy is a new idea in water resources research filed.Based on the virtual water theory,the virtual water content of main crops of 2008 was calculated and analyzed in Henan Province.The results indicated that the total amount of virtual water content of the agricultural products was not only related with the virtual water content per unit of product,but also with the total output of crops.Moreover,there existed spatial differences of the virtual water content for different regions and different farm products,and the spatial differences also existed in the same crop.Thus it provided new ideas and methods to adjust the structure of agriculture,to improve the competitiveness of agriculture,and to relieve regional water stress using virtual water strategy in Henan Province.
