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.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： ① the 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.
