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 variation 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%.
