摘　　要：利用2016—2022年阜阳市统计年鉴数据,采用排放因子法对阜阳市稻田甲烷排放、农用地氧化亚氮排放、动物肠道发酵甲烷排放以及动物粪便管理甲烷和氧化亚氮排放进行核算,采用误差传递法对结果进行不确定性分析,揭示主要排放源排放规律。结果表明,2016—2022年阜阳市农业温室气体排放量从342.32万t(CO_(2))e减少至298.35万t(CO_(2))e,减幅12.8%,但2018—2022年总体呈增加趋势,2022年排放量比2018年增加了13.6%,稻田、农用地、动物肠道发酵和动物粪便管理系统温室气体排放量分别占农业温室气体排放量的20%、30%、23%、27%,表明农用地氧化亚氮是阜阳市农业温室气体排放的主要来源,畜牧业温室气体排放呈增长趋势。Using the statistical yearbook data of Fuyang City from 2016 to 2022,the emission factor method was used to calculate the methane emissions from rice paddies,nitrous oxide emissions from agricultural land,methane emissions from animal intestinal fermentation,and methane and nitrous oxide emissions from animal manure management in Fuyang City.The error propagation method was used to analyze the uncertainty of the results and reveal the emission patterns of the main emission sources.The result showed that the agricultural greenhouse gas emissions in Fuyang City decreased from 3.4232 million t(CO_(2))e to 2.9835 million t(CO_(2))e from 2016 to 2022,a decrease of 12.8%.However,there was an overall increasing trend from 2018 to 2022,with emissions in 2022 increasing by 13.6%compared to 2018.The proportions of greenhouse gas emissions from rice paddies,agricultural land,animal enteric fermentation and animal manure management were 20%,30%,23%and 27%of the total agricultural emissions,respectively.The results indicated that nitrous oxide from agricultural land was the main source of agricultural greenhouse gas emissions in Fuyang City,and emissions from animal husbandry were on the rise.
