摘　　要：通过对新疆维吾尔自治区2011—2020年主要农作物秸秆的生态足迹动态变化研究得出:2011—2020年,新疆小麦、棉花、玉米秸秆资源总人均生态足迹变化范围较小。总人均生态足迹呈现出较高的水平。同时这3种秸秆人均总生态承载力有着明显波动。对新疆主要3种秸秆资源的综合利用方式的能值生态足迹进行了评估,结果呈现出,还田>饲料化>其他>生活燃料>肥料化。对新疆秸秆资源的利用要采取合理的规划,根据不同地区,不同的种植作物展开不同的利用方式,再将秸秆利用率增加的同时,坚持可持续性发展,实现生态效益与经济效益的共同发展,使得新疆生态经济系统转为生态盈余。Based on the dynamic change of ecological footprint of main crop straw in Xinjiang Uygur Autonomous Region from 2011 to 2020,it was concluded that the change range of the total per capita ecological footprint of wheat,cotton and corn straw resources was small in Xinjiang from 2011 to 2020.The total per capita ecological footprint showed a relatively high level.At the same time,the per capita total ecological carrying capacity of these three kinds of straw fluctuated significantly.In this paper,the emergy ecological footprint of three main comprehensive utilization methods of straw resources in Xinjiang was evaluated,and the results showed that returning to farmland>feed>other>domestic fuel>fertilizer.Later,reasonable planning should be adopted for the utilization of straw resources in Xinjiang,and different utilization methods should be developed according to different regions and different planted crops.Then,while increasing the utilization rate of straw,sustainable development should be adhered to to realize the common development of ecological and economic benefits,so that Xinjiang's ecological economic system will turn into ecological surplus.
