摘    要:针对现有生态足迹未考虑CO2排放承载力的问题,从碳吸收角度将净初级生产力与生态足迹法相结合,构建了CO2排放承载力计算模型,据此对吉林省近15年的CO2排放承载力进行了动态分析.结果显示,1994~2008年,吉林省人均CO2排放承载力从2.0345h㎡减少到1.9504h㎡,呈先升后降波动变化趋势.在CO2排放承载力构成中,林地、耕地、草地是主体,三者合计占89.54%~94.43%;草地变化最大,从0.5692 h㎡减少到0.1857 h㎡,降幅达67.38%;低生产力土地面积和草地面积均与人均CO2排放承载力呈极显著相关(R2=0.806、0.716),低生产力土地扩张和草地退化是人均CO2排放承载力下降的主要影响因素.研究表明,CO2排放承载力模型反映了自然环境对能源废弃物的消纳能力,符合区域资源禀赋的实际情况.

关 键 词:生态足迹  CO2排放承载力  净初级生产力  吉林省

Abstract:To solve the problem of ignoring CO_2 emission carrying capacity(CECC) in traditional ecological footprint,we constructed a CECC model by combining net primary productivity with ecological footprint method from a standpoint of carbon absorption,taking Jilin Province as a case study.The results showed that during 1994 and 2008,the CECC per capita decreased from 2.0345 hm~2 to 1.9504 hm~2,showing a fluctuation with rising first and declining afterwards.In the composition of CECC,forest,arable land and grazing...
Keywords:ecological footprint  CO_2 emission carrying capacity  net primary productivity  Jilin Province
