Abstract: |
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). |
