基于生态足迹的吉林省生态脆弱性分析

Analysis on the ecological vulnerability of Jilin Province based on ecological footprint

提出运用生态足迹的方法对区域生态脆弱性进行评价的观点,并对吉林省2007年的生态足迹进行了计算。结果表明:生态足迹为1.805975hm2/人,可利用的生态承载力面积为0.663971hm2/人,前者是后者2.72倍,表现为较强的脆弱性。其中,化石燃料的用地需求为1.041998hm2/人,占总需求的57.7%,超出了总的生态承载能力,城市生物资源消费产品的生态足迹为0.464208hm2/人,农村生物资源消费的生态足迹为0.431932hm2/人,前者略高于后者。另外,根据吉林省生态脆弱性的评价结果,提出了本区提高生态承载力,降低生态足迹的具体措施。最后,总结了生态足迹分析方法的优势以及进一步研究的方向。

The viewpoint that applying the ecological footprint method to evaluate ecological frangibility was put forward,and Jilin Province＇s ecological footprint was calculated.Results showed that acreage of ecological footprint is 1.805975hm^2/per capita,available acreage of ecological carrying capacity is 0.663971hm^2/per capita,the former is 2.72 times that of the latter,it has strong vulnerability.The land demand of fossil fuel is 1.041998hm^2/per capita,accounting for 57.7 percent of total demand,has exceeded all the ecological carrying capacity.The ecological footprint of mostly biologic expendable of town is 0.464208hm^2/per capita,and the ecological footprint of main agricultural products of the country is 0.431932hm^2/per capita,the former is slightly higher than the latter.Finally,the direction of further study of the ecological footprint analysis was summed up.
