中文摘要：

基于农地利用、稻田、牲畜养殖三方面17类碳源,测算了湖北省全省1995-2011年及其16个地市（州）2010年的农业碳排放量,并展开时空比较分析;在此基础上,利用LMDI模型对湖北省农业碳排放的驱动因素进行了分解。结果表明：湖北省全省2011年农业碳排放量达到1 544.90万t,较1995年（1 443.56万t）增加了7.02%,年均递增0.43%,呈现较为明显的＂上升-下降-上升＂的3个阶段变化特征;地市（州）间区域差异明显。根据碳排放的比重差异,将16个地市（州）划分为稻田主导型、农地利用主导型、牲畜养殖主导型、复合因素主导型4种类型;与1995年相比,效率、劳动力、结构因素分别实现了94.13%、41.23%和8.67%的农业碳减排,而经济因素则引发了151.05%的碳增量。

英文摘要：

Based on 17 classes of carbon resources from three aspects for agricultural land use, paddy fields and livestock, this paper estimates agricultural carbon emissions in Hubei Province from 1995 to 2011 and agricultural carbon emissions in 16 regions（city, autonomous prefectures） in 2010, and then makes the space-time comparative analysis. From the previous work, LMDI model is used to decompose the driving factors of agricultural carbon emissions in Hubei province. The result shows that agricultural carbon emissions of Hubei Province reached 15,449,000 tons in 2011, an increase of 7. 02% compared to 1995 （14,435,600 t）,and an average annual increase of 0. 34% ,which shows obvious three phase varia- tion of ＂up-down-up＂ in 2011 and regional differences are significant in horizontal comparison. Based on the differences in the proportion of carbon emissions, these 16 regions are divided into four types：paddy oriented type,agricultural land use oriented type, livestock oriented type and composite factors oriented type. Compared with 1995, the efficiency, the labor, and structural factors, respectively achieved 65.32 %, 28. 62% and 6.02% of agricultural carbon emission reduction,while economic factors led to carbon increase of 151.05%.
