| 中文摘要 |
| 根据收集的珠江三角洲（珠三角）人为氨源的活动水平数据，采用合理的估算方法和排放因子，建立了该地区2006年人为氨源分类别和分城市的排放清单.结果表明:①2006年珠三角地区人为氨源NH3排放总量约为194.8kt;②农业源是珠江三角洲地区人为氨源的主要排放贡献源,其中畜禽源排放的NH3占总排放量的62.1%,其次是氮肥施用源,其贡献率为21.7%;③畜禽源中肉鸡是NH3排放最大贡献源，占畜禽源NH3排放总量的43.4%，其次是肉猪，其贡献率为32.1%;④广州是珠三角地区2006年人为氨源排放量最大的城市，其次是江门，分别占NH3总排放量的23.4% 和19.1%,主要的排放源均为畜禽和氮肥施用源. |
| 英文摘要 |
| Based on the collected activity data and emission factors of anthropogenic ammonia sources, a 2006-based anthropogenic ammonia emission inventory was developed for the Pearl River Delta (PRD) region by source categories and cities with the use of appropriate estimation methods. The results show: ①the total NH3 emission from anthropogenic sources in the PRD region was 194.8kt; ②the agriculture sources were major contributors of anthropogenic ammonia sources, in which livestock sources shared 62.1% of total NH3 emission and the contribution of application of nitrogen fertilizers was 21.7%; ③the broiler was the largest contributor among the livestock sources, accounting for 43.4% of the livestock emissions, followed by the hog with a contribution of 32.1%;④Guangzhou was the largest ammonia emission city in the PRD region, and then Jiangmen, accounting for 23.4% and 19.1% of total NH3 emission in the PRD region respectively, with major sources as livestock sources and application of nitrogen fertilizers. |
