喀什地区生态足迹分析及其在生态规划中的应用

Ecological Footprint and Its Application in Ecological Planning in Kashgar Prefecture

生态足迹是一种定量测算人类对自然资源利用程度的方法。应用生态足迹理论,采用相关的计算方法,对喀什地区2000—2009年的生态足迹动态过程以及生态安全现状进行了计算并进行了预测分析。结果表明:当前喀什地区处于不可持续发展状态;按传统发展模式,喀什地区人均生态足迹在2016年将达到2.86 hm2,是2000年的14倍;喀什地区各县市的生态足迹对环境造成的压力存在着显著的空间差异;农牧业产品消费持续增高是生态足迹扩大的主要原因。

Ecological footprint is a method to quantitatively measuring the utilization degree of natural resources.In this paper,the theory,calculation methods and calculation models of ecological footprint were used to calculate,predict and analyze the dynamic change process of ecological footprint in Kashgar Prefecture,Xinjiang,China during the period from 2000 to 2009.The results showed that the development in Kashgar Prefecture was unsustainable.It was predicted that the per capita ecological footprint under the traditional development mode in Kashgar in 2016 would be up to 2.86 hm2.and 14 times of that in 2000.The pressure on ecological environment,caused by ecological footprint,was quite different from different regions in Kashgar,and the sustained increase in consumption of agricultural products was the main reason of expanding the ecological footprint.The ecological security in Kashgar was assessed based on calculating the ecological footprint and analyzing the distribution pattern of ecological footprint in Kashgar,and the application of the ecological footprint theory in ecological planning in arid area was discussed.
