中文摘要:
      农业碳排放在碳排放总量中所占比重较大,随着武汉城市圈建设“两型”社会的深入推进,武汉城市圈农业碳减排已迫在眉睫。在计算2009—2016年武汉城市圈年农业碳排放总量的基础上,采用改进的Divisia指数分解农业碳排放影响因素,并定量分解其主要驱动因素。结果显示:武汉城市圈农业碳排放总量在2016年高达222×106t,相比于 2009年翻番,同时武汉城市圈2009—2016年农业碳排放强度呈现出明显的区域差异,其整体和各地区表现出三阶段的变化趋势。碳排放因素分解结果显示,城镇化进程和一般农业技术进步效应较明显地抑制武汉城市圈农业碳排放增长,而农业生产规模效应促进各地区的农业碳排放。笔者提出可以从差异化的农业碳减排措施、农村基础设施建设提升和农村剩余劳动力合理转移等方面推进武汉城市圈低碳农业建设。
英文摘要:
      Agricultural carbon emissions account for a large proportion of total carbon emissions.With in depth advancing of “Two Oriented” Society in Wuhan metropolitan area,it is urgent to reduce agricultural carbon emission in Wuhan metropolitan area.Based on the calculation of the total annual amount of agricultural carbon emission in Wuhan metropolitan area from 2009 to 2016,the paper uses the improved Divisia index to decompose its influencing factors of agricultural carbon emission and quantitatively decompose its main driving factors.The study finds that the total carbon emissions from agriculture in the Wuhan metropolitan area were as high as 2.22 × 106 t in 2016,which doubled compared with that in 2009.At the same time,the intensity of agricultural carbon emission in the Wuhan metropolitan area in 2009-2016 presents significant regional differences,showing a three stage change in the whole and the various regions.The decomposition results of carbon emission factors show that the urbanization process and the general effects of agricultural technological progress have significantly inhibited the growth of carbon emissions in Wuhan metropolitan area,while the scale effect of agricultural production has promoted the agricultural carbon emissions in all regions.The author proposes that the low carbon agriculture construction of Wuhan metropolitan area can be promoted from the differentiated measures of agricultural carbon emission reduction,the improvement of rural infrastructure construction and the rational transfer of rural surplus labor.
