摘　　要：选择联合国政府间气候变化专门委员会(IPCC)的部门方法和8大类能源,采用1990年至2009年的中国能源统计数据,按照自下而上的思路,对我国各省区的碳排放量进行估算,并从碳排放量、碳排放强度、人均碳排放量和碳排放密指标出发,深入分析了各省区碳排放的时空特征差异。以期对国内碳排放的时空特征分析,有助于决策者和能源分析家提高节能减排政策制定的有效性。Climate change is an issue that is currently under heated discussion.People believe that carbon emissions are closely related to global warming.Therefore,all nations should take responsibility for solving this problem.According to the Global Carbon Dioxide Emissions Report,released by the Netherlands Environmental Assessment Agency in 2008,China topped the list of CO2 emitting countries,accounting for about a quarter of global CO2 emissions.Anthropogenic CO2 emissions are mainly due to the use of fossil fuels.The amount of CO2 from fossil fuel combustion is an important indicator used to evaluate a country/region′s total CO2 emissions.In China,76.6% of CO2 emissions were from fossil fuel combustion,according to China′s National Climate Change Programme.Because of global concerns about carbon reduction,high carbon emissions have put great pressure on China′s economic development,environmental and ecological protection,and even its international image.Therefore,reducing carbon emissions is not only crucial to China′s sustainable development;it is also an urgent international concern.It is important to know how carbon emissions have changed in China to effectively control and reduce carbon emissions from energy consumption. Based on the sectoral approach of the Intergovernmental Panel on Climate Change（IPCC） and eight fuel categories,this paper makes a bottom-up estimate of provincial-level carbon emissions,using data from China from 1990 to 2009.It finds that the values estimated in this paper are higher than in the emission inventory of the International Energy Agency and China′s National Climate Change Programme.This paper also analyzes the spatial disparities and temporal changes in carbon emissions,carbon intensity,carbon per capita,and carbon density at the provincial scale.The results show that： 1） An increase in carbon emissions in the past twenty years is a serious problem in China.The spatial pattern of carbon emissions in China has undergone tremendous change over the past two decades.In
