- 摘要：通过调查收集各类人为源氨排放活动水平数据，选取合适的排放因子，建立了青岛市2019年人为源氨排放清单，分析了青岛市人为源氨排放贡献特征及分布特征.结果表明，2019年青岛市人为源氨排放总量为28.33×103 t，排放强度为2.51 t·km-2.其中，畜禽养殖是青岛市最主要的排放源，占全市氨排放总量的比例高达77.80%，其次为农田生态系统和废弃物处理，氨排放量分别占全市总量的7.64%和6.87%.2019年，平度市和莱西市氨排放量较高，分别占青岛市氨排放总量的34.18%和26.23%，而市北区和莱西市排放强度较高，分别达到7.26 t·km-2和4.74 t·km-2.从空间分布上，氨排放量较高的镇街主要分布在青岛市北部和西北部，而排放强度较高的镇街则集中在青岛市市区中部和北部地区.
- Abstract：Based on investigational activity data of various anthropogenic ammonia emission sources and source-specific emission factors, an ammonia emission inventory of Qingdao in 2019 was developed. The differences of spatial distribution and contribution characteristics of anthropogenic ammonia emissions in Qingdao was also analyzed. The results showed that the total anthropogenic ammonia emission in Qingdao in 2019 was 28.33×103 t with regional averaged emission intensity of 2.51 t·km-2. Livestock and poultry was the most important anthropogenic ammonia emission source, accounting for 77.8% of the total ammonia emissions. The farmland ecosystem and waste disposal were the second and the third contributors, accounting for 7.64% and 6.87% of the total ammonia emissions, respectively. In 2019, the counties of Pingdu and Laixi had much higher ammonia emissions than other counties, accounting for 34.18% and 26.23% of the total emissions in Qingdao, respectively. Whereas, the counties of Shibei and Laixi had the highest emission intensity, with values of 7.26 t·km-2和4.74 t·km-2, respectively. Spatially, higher ammonia emissions was located in towns and districts in the north and northwest of Qingdao, while higher ammonia emission intensity was distributed in the downtown and north of Qingdao.
