中文摘要 根据收集到的城市尺度排放源活动水平数据，采用排放因子法，基于"自上而下"和"自下而上"相结合的方式建立了河南省2013年大气氨排放清单，利用GIS技术进行3 km×3 km空间网格分配.结果表明，河南省2013年大气氨排放总量为1035.3 kt，排放强度为6.4 t ·km^-2；畜禽养殖和氮肥施用为主要氨排放源，分别占总排放量的52.71%和31.53%；畜禽养殖中肉牛、蛋禽和山羊为主要贡献源，分别占畜禽养殖排放总量的34.98%、16.63%和14.02%；不同城市排放源构成和排放强度不同；南阳市、周口市、商丘市和驻马店市是排放量较大的地级市，分别占全省总量的11.53%、9.84%、9.62%和9.57%；濮阳市和漯河市排放强度最大，分别达到10.7 t ·km^-2和10.2 t ·km^-2；空间分布特征显示，中东部地区排放量较高，西部地区相对较低，排放量较大的地区集中在平原地区和人口密集区域. 英文摘要 Based on the best available activity data at a city level from top down and bottom up methods, a 2013-based emission inventory of NH₃ was established for the Henan Province using an emission factors method. The 3 km×3 km spatial gridded distribution was carried out by using GIS technology. The results showed that the total amount of atmospheric NH₃ emission in Henan Province in 2013 was 1035.3 kt, and the average emission intensity reached levels of 6.4 t/km². Livestock and nitrogen fertilizer applications were the top two emission sources, accounting for 52.71% and 31.53% of the total emissions, respectively. Beef, laying hen, and goats were the main contributors in the livestock category, accounting for 34.98%, 16.63%, and 14.02% of the total emissions, respectively. There were different characteristics between emission source contributions and emission intensities in each city. Nanyang, Zhoukou, Shangqiu, and Zhumadian were the prefecture-level cities with large emissions, accounting for 11.53%, 9.84%, 9.62%, and 9.57% of the total amount in Henan Province, respectively. The NH₃ emission intensities of Puyang and Louhe were larger than those of other cities, reaching up to 10.7 t·km^-2 and 10.2 t·km^-2, respectively. The spatial distribution revealed that emissions in the middle eastern region were relatively higher; whereas, the western region emissions were relatively low. The areas with high emissions were concentrated in the plains and densely populated areas.
