摘　　要：为探明我国烟草农业碳排放特征,推进烟草农业绿色低碳体系构建,基于农户调研数据,利用农业碳足迹理论定量分析豫南烟区烟叶农户生产碳足迹,明确农户在烟草生产过程中碳排放特征,研究豫南烟区烟草生产肥料碳足迹与单位面积产值的关系,烟叶单位面积产量与不同功能单位碳足迹的关系。结果表明,豫南烟区烟草生产系统单位面积、单位产量、单位产值碳足迹以CO_(2)当量(CO_(2)-eq)计,分别为12 630.03 kg CO_(2)-eq·hm^(-2)、6.62 kg CO_(2)-eq·kg^(-1)、0.21 kg CO_(2)-eq·￥^(-1);烘烤用煤、烘烤用电、农膜、肥料施用是豫南烟区烟草生产碳足迹的主要来源,分别占比67.4%、14.5%、6.1%、4.0%;基于单位面积高产值,28.04%调研农户的肥料碳足迹和氮肥碳足迹过高;基于烟叶低单位面积碳足迹,20.56%农户产量过低。因此,保持烟叶产量的同时,减少生产环节碳排放是豫南烟区发展绿色烟草农业的关键,推广清洁能源烤房、肥料优化管理将成为未来豫南烟区绿色烟草生产的重要举措。In order to study the characteristics of carbon emission of tobacco production in China and promote green low-carbon system for tobacco production,the tobacco carbon footprint in southern Henan tobacco growing area was quantitatively analyzed based on the agricultural carbon footprint theory and farmers’survey data.The characteristics of carbon emissions in the tobacco production process were clarified,and the relationship between the carbon footprint of tobacco production fertilizers and the output value per unit area,and that between tobacco yield per unit area and the carbon footprint of different functional units in the southern Henan tobacco growing area were analyzed.The results showed that the carbon footprints per unit area,per unit yield,and per unit production value of the tobacco production system in southern Henan were 12630.03 kg CO2-eq·hm-2,6.62 kg CO2-eq·kg-1,and 0.21 kg CO2-eq·¥-1,respectively.Coal used for tobacco curing,electricity for tobacco curing,agricultural film,and fertilizer application were the main sources of the carbon footprint of tobacco production in southern Henan,accounting for 67.4%,14.5%,6.1%,and 4.0%,respectively.Based on the higher output value per unit area,the carbon footprints of fertilizer and nitrogen fertilizer were found to be too high for 28.04%of the farmers surveyed.Based on the lower carbon footprint per unit area,tobacco yield was too low for 20.56%of the farmers surveyed.Therefore,the key to developing green tobacco production in southern Henan tobacco growing area is to maintain tobacco yield and reduce carbon emissions in production,and promoting clean energy curing houses and optimizing fertilizer management will be important measures for green tobacco production in the future.
