| 摘要: |
| 【目的】为了分析河南省主要农作物生产水足迹的利用情况和造成河南省农作物水足迹差异的影响因素,【方法】采用水足迹理论和方法,分析了在2012-2021年河南省主要农作物水足迹的时空演变情况和特征,并且运用通径分析法对河南省主要农作物水足迹空间变化影响因素进行研究。【结果】结果表明：在时间方面,2012-2021年河南省主要农作物水足迹大小排列为：小麦＞玉米＞花生＞稻谷＞大豆；在水足迹结构方面,河南省主要以绿水足迹为主,其中小麦的蓝水足迹和绿水足迹均是最大的,大豆是绿水足迹最小的农作物,玉米是蓝水足迹最小的农作物；在空间分布方面,蓝水足迹是东高西低分布,绿水足迹由北向南、由东向西方向逐渐增加,总水足迹是“四周高,中间低”的现象；此外,对河南省水足迹影响最大的因素是平均降水量。【结论】可通过调整河南省农作物种植布局,大力发展节水型农作物,来提高河南省农业水资源利用效率。 |

| Abstract: |
| [Objective] In order to analyze the utilization of water footprint of main crops in Henan Province and the influencing factors for the difference of water footprint of crops in Henan Province, [Method] The water footprint theory and method were used to analyze the spatial-temporal evolution and characteristics of the water footprint of major crops in Henan Province during 2012-2021, and the influencing factors of the spatial change of the water footprint of major crops in Henan Province were studied by path analysis method. [Results] The results showed that: in terms of time, the order of water footprint size of major crops in Henan Province from 2012 to 2021 was wheat > corn > peanut > rice > soybean.In terms of water footprint structure, the green water footprint in Henan Province was mainly dominated by wheat, soybean and corn, which had the largest blue water footprint, the smallest green water footprint.In terms of spatial distribution, blue water footprint was high in the east and low in the west, while green water footprint gradually increased from north to south and east to west. The total water footprint was a phenomenon of "high around and low in the middle".In addition, average precipitation was the most important factor affecting the water footprint of Henan Province. [Conclusion] The utilization efficiency of agricultural water resources in Henan Province can be improved by adjusting crop planting layout and vigorously developing water-saving crops. |
