摘　　要：选取云南省2010−2019年农作物生产播种面积、产量和作物生长过程中农资投入品等统计数据,估算农作物生产过程农资投入品所引起的碳排放量,分析其碳排放动态变化特征,各投入品在总碳排放中所占的比例,以及农资投入品碳排放的影响因素。结果表明:2010−2019年云南省农作物生产农资投入品碳排放量和碳排放强度以2016年为转折点,整体呈倒“U”型变化趋势,碳效率在2016年后上升趋势明显;在农资投入品中,化肥碳排放量占比最大,约占总排放量的60.35%,农膜、柴油、农药和灌溉分别约占总碳排放的17.55%、12.77%、8.25%和1.08%。国家政策、农作物种植结构、市场需求、科学种植技术和农业生产管理制度等因素对农作物生产农资投入品的碳排放变化有十分重要的影响,应加强国家政策引导和提高农作物生产技术水平,建立成熟的农业管理制度,合理规划农作物种植结构,减少农业生产碳排放量,促进农业绿色发展。Statistical data from Yunnan province between 2010 and 2019,including crop production sown area,yield and agricultural input materials during crop growth were selected to estimate the carbon emissions caused by agricultural inputs in the crop production process.The dynamic changes in carbon emissions,the proportion of each input in total carbon emissions,and the influencing factors of carbon emissions from agricultural inputs were analyzed.The results indicated that the carbon emissions and carbon emission intensity of agricultural inputs in crop production in Yunnan province from 2010 to 2019 showed an inverted“U”trend,with 2016 as the turning point,and a significant increase in carbon efficiency observed after 2016.Among the agricultural inputs,fertilizer contributed the most to carbon emissions,accounting for approximately 60.35%of the total emissions.Agricultural film,diesel,pesticides and irrigation accounted for approximately 17.55%,12.77%,8.25%and 1.08%of the total carbon emissions,respectively.National policies,crop planting structure,market demand,scientific planting techniques and agricultural production management systems had a significant impact on the changes in carbon emissions from agricultural inputs in crop production. It is recommended to strengthen national policy guidance, improve crop production technology levels, establish a mature agricultural management system, reasonably plan crop planting structures, reduce carbon emissions from agricultural production and promote green agricultural development.
