摘　　要：采用政府间气候变化专门委员会(IPCC)推荐的碳排放数学模型,根据2001-2010年中国电力能源实物消费量测算碳排放量和碳排放强度,研究电能消费碳排放强度的演变特征和产业间差异性。结果表明:电能消费碳排放总量从2001年0.3035Gt逐年上升至2010年0.7454Gt,平均增长9.99%。碳排放强度从276(kg/万元)波动下降至182kg/万元,平均下降4.42%。第二产业电能消费碳排放量和碳排放强度始终占据主导地位,碳排放量平均增长9.77%,碳排放强度平均下降4.95%;2010年工业部门的电能消费碳排放量为0.5488Gt、占总排放量的73.62%,碳排放强度为341kg/万元。第二产业及其工业部门电能消费碳排放强度明显超过第一、第三产业;但是第三产业碳排放的快速增长值得关注。期望为优化电力能源结构、发展生态产业经济以及制定行业间差异化的碳排放调控政策提供参考。The methodology in GHG inventory guidelines provided by the intergovernmental panel on Climate Change （ IPCC）, was used to estimate the carbon dioxide （ CO2 ） emissions and emission intensity of electronic energy consumption in China from 2001 to 2010. The characteristics of spatial disparity and temporal change of carbon emissions and carbon emission intensity from electronic energy consumption were analyzed on national, provincial and industrial level. The results indicate that： （1）Total carbon emission of electronic energy consumption in China has increased from 0. 3035Gt in 2001 to 0. 7454Gt in 2010, an annual increase of 9.99%. While carbon emission intensity has decreased from 276kg/（ 104 yuan） to 182kg/（ 104 yuan）, an annual decrease of 4.42%. （2）The carbon emission of secondary industrial electronic power consumption in China has accounted for the largest portion of total carbon emissions over the past decades, the annual average growth rate of 9.99%, the carbon emission were 0.5488 Gt in 2010, account for 73.62%. Also the carbon emission inten- sity of secondary industry were the heaviest in all industrial sectors, the annual average decline rate of 9.99%, the carbon intensity were 341 kg/（ 104 yuan） in 2010. The manufacturing of secondary industry is the main factor causing the carbon emission and carbon emission intensity, while tertiary industry＇s effect on reducing the carbon emissions and carbon emission intensity exceeds the impact of secondary industry on it.
