近10年中国不同区域CO2排放现状和特征

基于我国碳排放约束性指标的提出，在收集2000~2009年西部、中部、东北部及东部地区所辖30个省市（除西藏外）的相关数据的基础上，估算CO₂排放情况，通过图表及有关参数分析这些区域CO₂排放现状，阐明CO₂排放特征.结果显示，近10年，我国单位GDP CO₂排放量下降了38.4%，若兑现2020年碳减排承诺，减排量相当于2005年全球CO₂排放量的29.7%~33.4%；中国不同区域CO₂排放强度总体上呈逐年下降趋势，各区域CO₂排放强度与人均GDP呈一定的负相关性.历年来各区域CO₂排放强度占同期全国总值的比重均相对稳定，西部地区所占比重最多（占32%~34%），将是今后做好全国碳减排工作的一个重要区域.各区域二氧化碳年排放量增速与GDP增速曲线基本呈倒U型，符合环境库兹涅茨曲线.人均CO₂排放量呈逐年增加趋势.东部地区及东北部地区人均二氧化碳排放量明显高于西部、中部地区，该指标与经济的发达程度呈正相关性.各区域内人均贡献一份GDP上所排放的二氧化碳逐年递减，说明经济发展和节能减排能实现双赢，但与发达国家仍存在差距.

The present situation and characteristic of CO2 emissions in different region of China over the past decade

Based on the binding targets of Chinese carbon emissions,we adopted the related data of 30 provinces and cities(Tibet excepted) in the west,mid,northeast and east of China over the past decade to analyze the present situation and the characteristics by the amount of CO2 emissions for unit GDP in China(which is CO2-emissions-intention).The result showed that CO2-emissions-intenty in China descended 38.4% over the past decade.If China could cash the promise of reducing CO2 emissions,the quantity will be equal to 29.7%~33.4% of global share of carbon emissions in 2005.In the four regions,CO2 emissions intensity were almost dropping year by year.While there was negative correlation between CO2 emissions intensity and the Per capita GDP.There are no significant changes of the ratio of CO2-emissions-intenty in the four part regions occupied that in the whole country.The ratio of CO2-emissions-intenty in the west of China is maximum(for 32%~34%),where would become the operative important region to complete national reducing mission of CO2.The speed-up of CO2 emissions is related to GDP per year in inversed "U" pattern,which matchs the environmental Kuznets Curve.The mount of CO2 emissions for Per capita has the trend to increase,which in the East and Northeast is obviously higher than West and Central,and that presents positive correlation with the developing degree of economic.The result showed that the mount of CO2 emissions for Per capita related with Per capita GDP is dropping year by year,that means economic development and emissions reduction can win-win.
