【摘要】 通过对２０世纪９０年代中国几个主要温室气体研究项目中关于二氧化碳（ＣＯ２）排放源研究结果的综合分析，结合最新资料，对１９９０年的中国ＣＯ２排放源进行了收集和完善，对１９９４年中国 ＣＯ２排放源重新做了计算。其中，工业生产过程的ＣＯ２排放，在以前的研究中仅仅计算了水泥一项，本研究中我们增加了石灰、钢铁、电解铝三项，力求使结果更接近实际情况。结果表明，１９９０年和１９９４年中国ＣＯ２矿物燃料燃烧和工业过程总排放分别为２２１８．９×１０６ｔ（合６０５．１×１０６ｔ碳）和 ２７８７．８×１０６ｔ（合 ７６０．３×１０６ｔ碳），分别占当年全球ＣＯ２总排放的１０２％和１２７％。能源和工业生产活动的ＣＯ２排放均有不同程度的增长。矿物燃料燃烧是中国ＣＯ２的最大排放源，占总排放的９０％以上。对ＣＯ２排放源的不确定性分析表明，中国ＣＯ２排放存在大于１０％的减排潜力。更多还原

【Abstract】 Through summarizing the results of CO2 emission in several projects researching on green house gases emissions in China, emission of CO2 in 1990 in China is collected and improved. We calcu- late the emission from industrial producing process of lime, steel, and electroanalysis aluminum besides producing process of cement in previous research projects. Then the emission of CO2 in 1994 in China is calculated with updated data. The results show that in China the emissions of CO2 in 1990 and 1994 are 2218,9 Tg and 2787.8 Tg respectively which account for 10.2% and 12.7% of the world total CO2 emis- sions in the corresponding years. Emissions of CO2 from energy using and industrial activities increase by various extents. The main emission of CO2, which account for 90% of total emission, is from mineral fuel combustion in energy using. Analyses on the uncertainty of CO2 emissions shows that the potential mitigation of CO2 emission in China exceeds 10%.更多还原
