- 摘要：根据各类氨排放源的活动水平和排放因子,估算了2004年长江三角洲地区16个城市的氨排放量.结果表明,2004年长三角地区氨排放量为460.68kt,其中,氮肥使用和畜牧源是两个最大排放源,氨排放量分别为227.33kt和203.28kt,分别占长江三角洲地区氨排放总量的49.3%和44.1%.氨排放在长三角地区各城市间有较大差异,排放量超过40kt·a-1的城市为南通市、上海市、嘉兴市和泰州市,这4个城市的氨排放总量约占长三角地区氨排放量的42.5%.长江三角洲地区氨平均排放强度为4
- Abstract：The ammonia emissions of 16 cities in the Yangtze River Delta (YRD) in 2004 are estimated based on the activity data and emission factors of various ammonia sources. Results show that the anthropogenic ammonia emissions in the YRD reached 460.68 kt in 2004. The application of nitrogenous fertilizer and animal husbandry were the two largest contributors of ammonia emissions in the YRD,emitting 227.33 kt and 203.28 kt,respectively which represents 49.3% and 44.1% of the total ammonia emissions. The cities with ammonia emissions exceeding 40 kt·a-1 include Nantong,Shanghai,Jiaxing and Taizhou,which together contribute 42.5% of the total ammonia emissions. The average ammonia emission intensity in the YRD reached 4.20 t·km-2·a-1 in 2004. The cities whose emission intensity of ammonia exceeded 6 t·km-2·a-1 include Jiaxing,Nantong,Taizhou and Shanghai. The highest emission intensity was in Jiaxing,which was 10.83 t·km-2·a-1.
