【摘要】：以生命周期评价(LCA)为基础,选取农业能耗状况(化肥、农药、农膜施用强度)、农业生产低碳绩效(碳生产力、财政支农强度、农业碳排放效率)等评价指标,运用趋势分析法、对比分析法等分析安徽省低碳农业发展现状,并对低碳农业中化肥、农药、农膜使用量等影响因素进行回归分析。结果表明,2000—2014年安徽省农业生产中化肥、农药、农膜等碳排放源的排放强度均呈现逐年下降趋势,碳生产力逐年良性发展,农业碳排放效率逐年提高,农业碳排放总体呈正平衡状态。各因素对农业总产值的影响从大到小依次为化肥施用量、农药施用量、农膜施用量、农用柴油使用量,其各自用量每增加1%,农业总产值就相应地分别增加1.36%、1.14%、-0.70%、0.49%。
[Abstract]:Based on life cycle evaluation (LCA), agricultural energy consumption (chemical fertilizer, pesticide, agricultural film application intensity), low carbon performance of agricultural production (carbon productivity, financial support for agriculture) were selected. Agricultural carbon emission efficiency) and other evaluation indicators, using trend analysis, comparative analysis and other analysis of the development of low-carbon agriculture in Anhui Province, and low carbon agriculture fertilizer, pesticides. The results showed that the emission intensity of chemical fertilizer, pesticide, agricultural film and other carbon emission sources in agricultural production of Anhui Province from 2000 to 2014 showed a decreasing trend year by year. Carbon productivity has been developing well year by year, agricultural carbon emission efficiency has been improved year by year, and agricultural carbon emissions have a positive balance. The effects of various factors on agricultural output value from big to small are chemical fertilizer application and pesticide application. For each increase in the amount of agricultural film and diesel oil, the total agricultural output value increased by 1.36% and 1.14% -0.70%, respectively, and 0.49% of the total agricultural output value was increased.

【正文快照】： 低碳农业是当前应对气候恶化、生态危机时低碳经济背景下以低消耗、低污染、低排放、高效益、高碳汇为基础的新型农业发展形态,是农业可持续发展的升华。低碳农业既有别于过度依赖化肥、农药等生产资料的化学农业,又有别于强调回归自然、拒绝化学品的有机农业,也有别于适度使，
