城市生态足迹计算中温室气体环境责任的区域分配法

针对生态足迹方法应用于城市尺度时对温室气体处理上的不足,提出了除存在能源贸易调整的缺陷外,还应对城市的温室气体环境责任重新定义和划分,城市可持续发展应依照城市自身的区域特征来制定标准.在对城市尺度与国家尺度上生态足迹核算体系温室气体环境责任分配内涵的不同进行分析后,基于城市等级的划分和经济联系强度等概念,构建了在城市尺度上温室气体环境责任的区域分配法,使生态足迹方法应用在城市尺度的可持续评价上更加真实可靠.

Regional distribution approach for measurement on greenhouse gases environmental liability in urban ecological footprint

The research of ecological footprint method applied in national scale was more successful than applied in urban scale. Besides the defect of trade-correct, the environmental liability of greenhouse gases was ignored when ecological footprint was applied in urban scale. The standard of urban sustainable development should be redefined base on its regional characteristic, where the city belongs to. After analysis of environmental liability in ecological footprint frame between urban scale and national scale, the distribution method of greenhouse gases environmental liability in urban scale were constructed by classifying the cities and computing the index of economic relation intensity. This method could improve the credibility of ecological footprint model applied in urban scale.
