为探求河南省化石能源消耗及工业生产过程对省域碳循环影响,利用ORNL和EEA提出的区域碳排放和碳吸收定量模型,估算并分析2000-2009年河南省域碳均衡动态变化。结果表明:2000-2009年河南省碳排放量为119 295.76×10^4 t,其中化石燃料排放量占碳排放总量的92.3%,工业生产过程碳排放为7.7%;煤炭消耗是化石能源利用中最大碳源,占化石能源碳排放总量的89.53%,其次分别是水泥生产和原油耗用,燃料油消费碳排放量最小,仅占0.43%;近10年来河南省人均碳排放量逐步递增,并于2003年超出全国平均水平,同期万元GDP的碳排放强度先增后降,能源利用效率明显提高;河南省2009年林地碳吸收能力为387.57×10^4 t,近10年增长了67%,而同期碳排放量增加了1.925倍,导致省域碳赤字迅速增加,并于2009年达到12 886.92×10^4 t;最后提出了河南省碳减排的措施建议。
In order to explore the impact of carbon cycle in fossil fuel use and industrial production,this paper estimated the dynamic changes of the carbon emission and carbon absorption from 2000 to 2009 in Henan province based the quantitative model proposed by ORNL and EEA.The results showed that the total carbon emission in Henan province was 119 295.76×104 t during the 2000 to 2009,among which 92.3% came from fossil fuel combustion and 7.7% from industrial production process.The carbon emission from coal was the highest among all kinds of fossil fuels,occupying 89.53% of total emission from fossil fuel,the second and third was cement production and oil consumption respectively,and the contribution from fuel oil consumption was least,just 0.43%.The carbon emission increased progressively year by year during 2000-2009,and surpass the national average level in 2003,while the carbon emission for ten thousands yuan GDP was dropping by 25% at the same time.The carbon absorption was 387.57×104 t in 2009 in Henan,which increased by 67% during past 10 years,while the carbon emission increased to 1.925 times during the same time that led to carbon deficit growing rapidly,and reached at 12 886.92×104 t in 2009.Finally,this paper put forward some measures for the policy-making of carbon emission reduction in Henan province.
