基于能源消费的中国不同产业空间的碳足迹分析

【摘要】:采用2007年中国各省区不同产业各种能源消费等数据,通过构建能源消费碳排放和碳足迹模型,对各省区化石能源和农村生物质能源的碳排放量进行了估算;建立了不同产业空间与能源消费碳排放的对应关系,将产业活动空间分为农业空间、生活与工商业空间、交通产业空间、渔业与水利业空间、其他产业空间等五大类;对各省区不同产业空间碳排放强度和碳足迹进行了对比分析。主要结论如下:(1)中国2007年能源消费碳排放总量为1.65GtC,其中化石能源碳排放占89%;(2)2007年中国产业空间碳排放强度为1.98t/hm2,其中,生活及工商业空间、交通产业空间的碳排放强度较高,分别为55.16t/hm2和49.65t/hm2;(3)2007年中国产业空间碳足迹为522.34×106hm2,由此造成的生态赤字为28.69×106hm2,这说明我国的生产性土地面积不足以补偿产业空间的碳排放,补偿率约为94.5%。各地区碳足迹差异明显,不少省份甚至存在生态盈余。总体而言,从产业活动空间的角度来看,中国目前的碳赤字不大;(4)全国产业空间单位面积碳足迹为0.63hm2/hm2,其中生活与工商业空间的碳足迹最大,为17.5hm2/hm2。不同产业空间单位面积碳足迹大都呈现从东到西逐渐下降的趋势。

Carbon footprint of different industrial spaces based on energy consumption in China

Journal of Geographical Sciences , 02/2011

【Abstract】 Using energy consumption and land use data of each region of China in 2007,this paper established carbon emission and carbon footprint model based on energy consumption,and estimated the carbon emission amount of fossil energy and rural biomass energy of dif-ferent regions of China in 2007.Through matching the energy consumption items with indus-trial spaces,this paper divided industrial spaces into five types:agricultural space,living & industrial-commercial space,transportation industrial space,fishery and water conservancy space,and other industrial space.Then the author analyzed the carbon emission intensity and carbon footprint of each industrial space.Finally,advices of decreasing industrial carbon footprint and optimizing industrial space pattern were put forward.The main conclusions are as following:(1) Total amount of carbon emission from energy consumption of China in 2007 was about 1.65 GtC,in which the proportion of carbon emission from fossil energy was 89%.(2) Carbon emission intensity of industrial space of China in 2007 was 1.98 t/hm2,in which,carbon emission intensity of living & industrial-commercial space and of transportation in-dustrial space was 55.16 t/hm2 and 49.65 t/hm2 respectively,they were high-carbon-emission industrial spaces among others.(3) Carbon footprint caused by industrial activities of China in 2007 was 522.34 106 hm2,which brought about ecological deficit of 28.69 106 hm2,which means that the productive lands were not sufficient to compensate for carbon footprint of industrial activities,and the compensating rate was 94.5%.As to the regional carbon footprint,several regions have ecological profit while others have not.In general,the present ecologi-cal deficit caused by industrial activities was small in 2007.(4) Per unit area carbon footprint of industrial space in China was about 0.63 hm2/hm2 in 2007,in which that of living & indus-trial-commercial space was the highest (17.5 hm2/hm2).The per unit area carbon footprint of different industrial spaces all presented a declining trend from east to west of China.
