摘要
以中部典型省份湖南省为例,采用湖南省及14个地级市的煤炭、石油、天然气等能源消耗、水泥产量数据以及林地、草地等土地利用数据,基于碳均衡视角,利用碳排放、碳吸收、净排放测算模型,估算并模拟分析湖南省碳排放与碳吸收的时空差异。结果表明:(1)2000-2009年,湖南省碳排放总量年均增加523.98×104 t,其中,化石燃料燃烧碳排放占湖南省碳排放总量的比例长期稳定在85%以上,是最主要碳源;(2)2009年断面数据表明,湖南省碳排放总量存在明显的区域差异,其中,岳阳、娄底、郴州、衡阳、长沙、湘潭6市属高碳区,常德、益阳与株洲3市属中碳区,邵阳、怀化、永州、张家界与吉首5市属低碳区;(3)2003-2009年,湖南省碳吸收量呈现出小幅增长趋势,导致湖南省净排放迅速增加,由2003年的2 608.01×104 t增加到2009年的6 554.62×104 t,7年净排放累计为35 086.11×104 t;(4)2005年断面数据表明,湖南省碳吸收也存在明显的区域差异,其中怀化、永州、郴州与邵阳4市属高值区,衡阳、常德、株洲、张家界、长沙、岳阳及益阳7市属中值区,娄底、湘潭与吉首3市属低值区;(5)2003-2009年,湖南省碳排放与碳吸收之间未达到均衡状态,净排放由2003年的2 608.01×104 t增加到2009年的6 554.62×104 t。
Taking Hunan province for example,this paper estimated the spatial-temporal difference of carbon emission and carbon absorption in Hunan province based on the related data and the quantitative model.The results showed that：（1）The total carbon emission was increasing at average speed of 523.98×104 t/a.The carbon emission from fossil fuel consumption accounting the total for above 85% was the main carbon sources.（2）The amounts of carbon emission were different among regions in 2009.Yueyang,Loudi,Chenzhou,Hengyang,Changsha and Xiangtan belonged to the high carbon area,Changde,Yiyang and Zhuzhou belonged to the middle carbon area,Shaoyang,Huaihua,Yongzhou,Zhangjiajie and Jishou belonged to the low carbon area.（3）The carbon absorption was increasing by small speed.It resulted in quick increase of carbon deficit from 2 608.01×104 t in 2003 to 6 554.62×104 t in 2009.（4）The amounts of carbon absorption were also different among regions in 2005.Huaihua,Yongzhou,Chenzhou and Shaoyang belonged to the high area;Hengyang,Changde,Zhuzhu,Zhangjiajie,Changsha,Yueyang and Yiyang belonged to middle area;Loudi,Xiangtan and Jishou belonged to low area.（5）The equilibrium did not reached between carbon emission and absorption in Hunan province from 2003 to 2009.The net carbon emission increased from 2 608.01×104 t in 2003 to 6 554.62×104 t in 2009.
