摘　　要：通过2019年河北省人为氨排放源活动水平的统计数据,利用排放因子法构建了河北省人为源氨排放清单,并利用ArcGIS软件研究了氨排放量和排放强度的空间分布特征.结果表明,2019年河北省人为源氨排放量为767.52 kt,其中农业源氨排放量占到93.17%,主要与对肥料和粪便缺少有效处理有关.主要的氨排放源为畜禽养殖和化肥施用,其排放量分别占氨排放总量的69.59%和21.19%,其中畜禽养殖中肉禽对NH3的贡献最高,分担率高达37.04%.非农业源中人体排放与燃料燃烧排放源贡献较高,分别占2.03%和2.28%.2019年河北省氨平均排放强度为4.10 t·km^(-2),其中石家庄市氨排放量和排放强度最高,分别为116.73 kt和8.03 t·km^(-2).空间分布特征上,较高的氨排放量和排放强度均主要集中在河北省南部及中部地区.Based on the statistical data of the activity level of anthropogenic ammonia emission sources in 2019 of Hebei Province,the ammonia emission inventory of Hebei Province was established using the emission factor method.The spatial distribution characteristics of ammonia emissions and emission intensity were studied by ArcGIS software.The anthropogenic ammonia emissions in 2019 of Hebei Province were up to 767.52 kt,of which the agricultural sources ammonia accounted for 93.17%.This result is mainly attributed to the lack of effective treatment of fertilizers and manure agricultural.The breeding of livestock and poultry and the application of chemical fertilizer were main emission sources,accounting for 69.59%and 21.19%of the total ammonia emissions,respectively.Meat poultry had the highest contribution to NH3 with a sharing rate of 37.04%.For the non-agricultural sources,human and fuel combustion emissions had higher contributions with contribution rates of 2.03%and 2.28%,respectively.An average emission intensity in 2019 of Hebei Province was 4.10 t·km^(-2),of which Shijiazhuang had the highest ammonia emissions and emission intensity with averages of 116.73 kt and 8.03 t·km^(-2),respectively.The areas with higher ammonia emission and emission intensity mainly concentrated in the southern and central regions of Hebei Province.
