摘要
测算了1997-2007年中国30个省份分省化石能源的碳排放量、单位国内生产总值碳排放强度、人均碳排放强度和单位建设用地碳排放强度,得出如下结论:1)2007年的碳排放比1997年几乎增长一倍,带来了显著的环境效应。2)1997年以来,有25个省份单位国内生产总值碳排放强度总体呈下降趋势,但是大多数省份在2002年后,单位国内生产总值的碳排放开始小幅反弹。3)1997-2007年,除北京外,其余29个省份的人均碳排放强度呈现递增趋势,单位建设用地碳排放强度总体呈上升趋势。以上趋势与中国经济发展的"重型化"相对应,表明化石能源的消耗对环境的影响强度越来越大。
The urbanization and industrialization of China brings forth rapid expansion of built-up land and sharp increase of fossil-fuel consumption and carbon emission.In this paper,the total fossil-fuel carbon emission of each province was calculated and the carbon emission intensity of per-unit gross domestic product（GDP）,per capita and per unit area of built-up land was analyzed.The research shows that the total amount of carbon emission in 2007 is almost two times of 1997,which indicates that industrialization and urbanization in China speeds up the consumption of fossil-fuel,causing prominently negative environmental impacts.The carbon emission intensity of per-unit GDP has revealed the declining trend generally since 1997 but most of provinces show a little bit rebound after 2002.The carbon intensity per capita increased for all provinces except Beijing from 1997 to 2007.The carbon emission intensity of per unit area of built-up land gradually increased,which was consistent with the trend of heavy industry development,indicating that the intensity of environmental impact caused by the fossil-fuel consumption was becoming higher and higher.
