中国能源消费导致的CO_2排放量的时空演变分析

利用《IPCC2006国家温室气体清单指南》推荐的基准方法,结合能源消费统计数据,在省级尺度上对中国1997～2007年由于能源消费产生的CO2排放总量、CO2排放的分布、人均排放量、CO2排放强度等进行计算和对比分析。研究结果表明:(1)1997～2007年山东、河北、江苏、广东、辽宁、河南、山西等省的CO2排放总量一直居于前列。(2)中国能源消费产生的CO2排放主要集中在第二产业,而且第一、第二产业的CO2排放比重近年来有加大的趋势。(3)从CO2排放强度来看,中西部省区的CO2排放强度明显高于东部沿海省份。

Analysis of Spatio-temporal Characteristics of COZ Emission Induced by Energy Source Consumption in China

Using the calculation methodology adopted by the 2006 IPCC guidelines,in combination with the statistics data of energy consumption,we compared and analyzed the volume of carbon dioxide emissions,the distribution of carbon dioxide emissions,the carbon dioxide emissions per capita,carbon dioxide emission intensity during 1997~2007 on a provincial scale.The results indicate:(1) in 1997~2007 the volume of carbon dioxide emissions in Shandong,Hebei,Jiangsu,Guangdong,Henan,Shanxi provinces ranks the first.(2) carbon dioxide emissions mainly come from the secondary industry,the proportion of first and secondary industry's carbon dioxide emissions has increased in recent years, and (3) the carbon dioxide emission intensity of central and western provinces is obviously higher than the eastern coastal provinces.
