在GIS技术的支持下,通过对1978-2013年河南省冬小麦、夏玉米、花生、棉花、油料作物、蔬菜6种主要农作物虚拟水量的计算与分析,探讨了其时空分异规律。河南省6种农作物单位质量虚拟水量在不断下降的趋势下有波动,2003年出现峰值,与当年大旱、所有农作物大面积减产有关;在农作物类型中,棉花单位质量虚拟水含量最高,多年平均值达到8 077.4 m3/t,蔬菜最低,多年平均值仅为159.95 m3/t。6种作物的虚拟水含量在空间分布上有明显差异,按其2013年的产量进行加权分析得到,第一等级区域为三门峡、郑州、信阳,第二等级为平顶山、洛阳、济源、开封,第三等级为南阳、驻马店、新乡、鹤壁、安阳、濮阳,第四等级为漯河,最低为许昌、周口、商丘、焦作。从整体看,西部、南部虚拟水含量高,而北部、东部虚拟水含量低。

Based on GIS, the thesis discusses the regularity of time and region of the virtual water of 6 kindsof main crops in Henan Province from 1978 to 2013 through calculation and analysis. During 36 years in HenanProvince, virtual water of 6 kinds of crops is in the declining trend under the wave, and in 2003 reaches the peak.It has relation with the reduction of output because of drought. In crop types, which the virtual water highest is cot-ton, the average in many years reaches 8 294.3 m3/t, and vegetable is the minimum, average value is only 163.4m3/t. In the spatial distribution, 6 kinds of crops are different. According to the output of 2013, obtained byweight the first region is Sanmenxia, Zhengzhou, Xinyang, Pingdingshan, Luoyang, the second includes Jiyuan,Kaifeng, Nanyang, Zhumadian; and the third is Xinxiang, Hebi, Anyang, Puyang, the fourth grade is Luohe,Xuchang, Zhoukou, Shangqiu and the lowest is Jiaozuo. On the whole, the west, south virtual water is high, andthe virtual water is low in northeast.
