摘　　要：亳州市是黄淮平原典型城市,而农业是其最大的氨排放来源。基于亳州市畜禽养殖、氮肥施用、固氮植物、土壤本底、秸秆堆肥、人体粪便6类农业源活动水平数据与排放因子,建立2011—2018年亳州市农业源氨排放清单,分析该市氨排放结构、空间分布、历年变化趋势及不确定性,进一步深入了解黄淮平原典型城市农业氨排放特征。结果表明:2018年亳州市农业氨排放总量为27529.19 t/a,其中畜禽养殖与氮肥施用是农业氨排放量较大的2类源,占比分别为68.81%、16.85%。农业氨排放集中在利辛县与谯城区,分别占全市总排放量的28.9%、27.8%。亳州市农业氨排放量从2011年的35097.97 t/a小幅升至2014年的38441.13 t/a,2015—2017年变化不大,2018年降至27529.19 t/a。从各类农业源氨排放量变化趋势来看,2011—2018年秸秆堆肥、土壤本底的氨排放量出现微小涨幅,畜禽养殖、氮肥施用、固氮植物、人体粪便的氨排放量呈下降趋势。此外,2011—2018年亳州市农业源清单的不确定性处于-22%~26%,清单不确定性较小。Bozhou City is a typical city in Huanghuai Plain,and agriculture is the largest source of ammonia emission.In order to further understand the agricultural ammonia emission characteristics of typical cities in Huanghuai Plain,based on the activity data and emission factors of six types of agricultural sources including livestock and poultry breeding,nitrogen fertilizer application,nitrogen-fixing plants,soil background,straw compost and human manure,the ammonia emission inventory of agricultural sources in Bozhou City from 2011 to 2018 was established to analyze the emission structure,spatial patterns,historical trends and their uncertainties.The results showed that the total ammonia emissions from agricultural sources in Bozhou City in 2018 were 27529.19 t/a,of which livestock and poultry breeding and nitrogen fertilizer application were the two major sources of agricultural ammonia emissions,accounting for 68.81%and 16.85%,respectively.The emissions were concentrated in Lixin County and Qiaocheng District,accounting for 28.9%and 27.8%of the total emissions of Bozhou City,respectively.The total agricultural ammonia emissions of Bozhou City rose slightly from 35097.97 t/a in 2011 to 38441.13 t/a in 2014;from 2015 to 2017,there was little change;and in 2018,it decreased to 27529.19 t/a.Among various types of sources,ammonia emissions of straw compost and soil background showed a slight increase from 2011 to 2018,while livestock and poultry breeding,nitrogen fertilizer application,nitrogen-fixing plants,and human manure showed a decreasing trend.In addition,the uncertainty range of Bozhou agricultural ammonia emission inventory from 2011 to 2018 was between-22%and 26%,which was small.
