摘　　要：借鉴农业碳排放领域研究成果,研究安徽省农业碳排放,运用生命周期评价法(LCA)系统梳理安徽省农业2000-2013年度化肥施用量、畜禽养殖量、农药农膜使用量、土壤面积、农用机械总动力等碳排放活动,测算安徽省农田碳排放总量、碳排放结构与碳排放效率。结果表明,安徽省农业碳排放总量逐年缓慢上升,与农业发展趋势基本一致,上升幅度小于农业总产值上升幅度,整体而言安徽省农业系统碳排放处于正平衡状态;工业投入品碳排放是安徽省农业碳排放最重要的来源,其中化肥生产、运输、施用过程中引起的碳排放在整个农业碳排放系统中所占比重最大;农业碳排放强度呈逐年下降趋势,农业碳排放效率逐年提高。Using the research achievements in field of agricultural carbon emmissions for reference,the carbon emission source and factor of Anhui agriculture was identified by LCA. The fertilizer consumption, the amount of livestock, the amount of pesticide and plastic sheeting, soil area, the total power of agricultural machinery and other carbon activities of Anhui from 2000 to2013 were systematically combed to measure the carbon emissions of farmland in Anhui, the structure of carbon emissions and carbon emission efficiency. The results showed that the total agricultural emissions was gradually slowly rise in Anhui, and remained the same upward trend with agricultural development, and the rate of increase of was less than the rate of increase of agricultural output, overall carbon emissions of Anhui agricultural system was in the positive equilibrium state. Industrial inputs carbon emissions was the most important source of Anhui Agricultural greenhouse gases, and carbon emissions caused by fertilizer production, transport, application process emissions was the largest share of carbon emissions in Anhui entire agricultural system.Agricultural carbon intensity showed a declining trend, and the efficiency of agricultural carbon emissions increased every year.
