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1.65 GtC,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1.98 t/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55.16 t/hm2和49.65 t/hm2;(3) 2007 年中国产业空间碳足迹为522.34×106 hm2,由此造成的生态赤字为28.69×106 hm2,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0.63 hm2/hm2,其中生活与工商业空间的碳足迹最大,为17.5 hm2/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。

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 different regions of China in 2007. The main conclusions are as follows: (1) The 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 industrial space was 55.16 t/hm2 and 49.65 t/hm2 respectively. (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. (4) The per unit area carbon footprint of industrial spaces in China was about 0.63 hm2/hm2 in 2007.
