| 中文摘要: |
| 农业是新疆水资源消耗最大的产业。本研究应用水足迹理论对新疆83个县市主要农作物的生产水足迹进行研究分析，比较不同作物之间生产水足迹的差异，探讨新疆农业生产水足迹在空间上的变化规律。研究结果表明，全疆2014年主要农作物生产水足迹总量为355.47×108 m3，其中主要为蓝水足迹，所占比例高达91.31%；绿水足迹极低，所占比例仅为8.69%。7种主要作物生产水足迹由高到低分别是棉花，向日葵，小麦，水稻，玉米，苜蓿以及甜菜。水足迹空间分布在不同区域差异显著，南疆以及伊犁地区的生产水足迹总量相对较高，二者总量为243.46×108 m3，东疆和北疆地区水足迹总量相对较低，二者总量为112.01×108 m3，总体呈现出西南高东北低的分布趋势。 |

| Agriculture production consumes the most water resources in Xinjiang.In this study,we estimated the water footprints(WF) of primary crops from 83 counties and cities in Xinjiang based on water footprint theory, compared the WF variation among different crops and investigated the spatial regularity of agriculture water footprints, the results indicated that the water footprints (WF) of primary crops in 2014 was 355.47×108 m3 of that 91.31% was blue water footprints while the rest of 8.69% was green water footprints. The water footprints of the primary crops from high to low ranked as cotton, sunflower, wheat, paddy, maize, alfalfa, and beets. The water footprint varied significantly among regions. While WF is high in southern Xinjiang and Yili (243.46×108 m3) it was relatively low in northern and eastern Xinjiang (112.01×108 m3). |
