Assessment of energy ecological footprint of main crop straw resources in Xinjiang under different utilization methods
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.
