摘　　要：采用政府间气候变化专门委员会（IPCC）《国家温室气体清单指南》碳排放数学模型,测算了2001~2010年中国及各省电力能源消费碳排放量和碳排放强度,研究了省际间碳排放强度时空演变和差异性特征。结果表明：1）全国电能消费碳排放总量从2001年303Mt逐年上升至2010年745Mt,平均年增长9.99%;各省碳排放量呈增长趋势,2010年东部地区五省碳排放属超重型（≥40 Mt）;西部省份碳排放速度保持较快增长速度。2）全国电能消费单位GDP碳排放强度从276（kg/万元）下降至182（kg/万元）,平均年下降4.42%;西部省份碳强度普遍高于东部发达地区,说明西部经济发展对电能消费碳排放的依赖性强,东部地区电能消费低碳经济格局开始形成。省际间电能消费碳排放强度的差异性与资源禀赋、经济发展、人口状况、消费水平等因素相关,为我国制定差异化的区域节能减排目标和电力产业发展调控政策提供参考。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 power energy consumption in China from 2001 to 2010. The characteristics of spatial disparity and temporal change of carbon emissions and carbon emission intensity from power energy consumption were analyzed on national,provincial and industrial levels. The results indicated that： 1 total carbon emission of power energy consumption in China had increased from 303 Mt in 2001 to 745 Mt in 2010,an annual increase of 9. 99%. The carbon emission of every provincial power consumption in China showed basically an increasing trend over the past decades. In 2010,there were five provinces in eastern China where the carbon emissions were belong to extra- heavy type（ ≥40Mt）. The carbon emission of power consumption in western regions China kept rising rapidity all the way. 2While carbon emission intensity per GDP had decreased from 276 kg /（ 104yuan） to 182 kg /（ 104yuan）,an annual decrease of 4. 42%. The every provincial carbon intensity per GDP showed a decreasing trend in the past decade. The development capacity of low- carbon economy in western regions was less than that in eastern provinces. Disparity of carbon emissions in power production and consumption were closely related to the factors such as resources endowment,economy development,population status,and woodland area of provincial- level. The study of inter- provincial discrepancy and spatiotemporal characteristics provides insight into spatiotemporal heterogeneity of carbon emission of power energy in China,and also provides references for instituting differential regions objectives of carbon emission reduction and related regulation policies of power industry development.
