| 中文摘要 |
| 根据西安市各类氨排放源活动水平数据，采用合理的估算方法和排放因子，建立了2013年西安市人为源大气氨排放清单. 结果表明，2013年西安市人为源大气氨排放量为47.17×103 t，排放强度为4.57 t·km-2；畜禽养殖和氮肥施用是排放贡献最大的两个人为源，氨排放量分别为20.55×103 t和17.51×103 t，占排放总量的80.68%；畜禽养殖中，牛和猪是最大的排放源，占畜禽养殖排放总量的75.03%；临潼区是排放量最大行政区，排放量为10.73×103 t，分担率为23.22%；阎良区的排放强度最大，达到14.75 t·km-2. |
| 英文摘要 |
| Based on the activity data of diverse ammonia sources, the rational estimation method and emission factors were employed, and an anthropogenic ammonia emission inventory was further established to describe the situation of Xi'an in 2013.The results showed that the total anthropogenic ammonia emission reached 47.17×103 t in 2013 with an emission intensity of 4.57 t·km-2; The livestock breeding and nitrogen fertilizers were the major sources of anthropogenic ammonia emission, which were 20.55×103 t and 17.51×103 t, respectively, accounting for 80.68% in total; Cow and hog were the major sources, and occupied 75.03% in livestock breeding emission; Lintong District was the heaviest emission area, the total emission was 10.73×103 t, which accounted for 23.22%; The emission intensity of Yanliang District reached 14.75 t·km-2 which was considered as the most severe area. |
