【摘要】：农业废弃物资源的循环利用,对于实现农业资源的高效利用、转变农业经济增长方式、实现农业现代化具有重要的意义。运用能值分析与生态足迹相结合的方法,在科学估算新疆南疆棉区棉花秸秆资源储量的基础上,对南疆棉区2005—2014年棉花秸秆资源的各种利用方式进行评估,根据能值生态足迹相关理论,从时序上判断南疆棉区的人均生态足迹的变化趋势和不同利用方式人均生态承载力的载荷。结果表明:近10年来南疆棉花秸秆利用的总人均生态足迹为9.65公顷,总人均生态承载力为8.009公顷,年均生态赤字为1.641公顷;说明研究区棉花秸秆资源的利用方式较为粗放,与区域资源环境不协调,并且超出了研究区生态环境系统的承载能力,特别是在饲料化和肥料化的利用方式上较为粗放,资源浪费比较严重,需要政府政策的支持和农户的自主创新。
[Abstract]:The recycling of agricultural waste resources is of great significance to realize the efficient utilization of agricultural resources, to change the mode of agricultural economic growth and to realize agricultural modernization.On the basis of scientific estimation of cotton straw resource reserves in southern Xinjiang cotton region, various utilization methods of cotton straw resource in southern Xinjiang cotton region from 2005 to 2014 were evaluated by using the method of combining energy analysis with ecological footprint.Based on the theory of emergy ecological footprint, the change trend of per capita ecological footprint and the load of ecological carrying capacity per capita in different utilization modes of cotton region in southern Xinjiang were judged in terms of time series.The results showed that the per capita ecological footprint of cotton straw utilization in southern Xinjiang was 9.65 ha, the total per capita ecological carrying capacity was 8.009 ha, and the annual ecological deficit was 1.641 ha, indicating that the utilization of cotton straw resources in the study area was extensive.It is out of harmony with the regional resources and environment, and exceeds the carrying capacity of the ecological environment system in the study area, especially in the way of utilization of feed and fertilizer, and the waste of resources is serious.Need the support of government policy and farmer independent innovation.
