2006~2014年江苏省氨排放清单

为了解江苏省氨排放情况，收集了畜禽养殖、氮肥施用、人体排放、工业生产、机动车排放、燃料燃烧、生物质燃烧、垃圾和污水处理等9类氨源的活动水平数据，并基于排放因子法，估算了2006~2014年江苏省氨排放清单，分析了其历年来氨排放的变化趋势及空间分布特征.结果表明，江苏省的氨排放量由2006年的654.4kt增加到2014年的729.8kt，年均增长率约为1.41%.氮肥施用和畜禽养殖一直是江苏省最主要的氨排放源，共占2014年江苏省氨排放总量的88.19%；非农业源中，由机动车排放及生物质燃烧产生的氨排放增长速度最快.2014年江苏省氨平均排放强度为4.4t/（km²·a），其结果明显高于我国氨排放强度平均水平.

Estimation of ammonia emissions inventories in Jiangsu province from 2006 to 2014

The ammonia emission sources such as the livestock, the fertilizers' application, human body emission, industrial production, vehicle emission, fossil fuel burning, biomass burning, the treatment of sewage and waste were collected in Jiangsu province. The ammonia emissions inventories were established from 2006 to 2014 based on emission factors method. The trend, temporal and spatial characteristics of ammonia emission were analyzed. The total ammonia emission in Jiangsu province was proved to change from 654.4 kt in 2006 to 729.8 kt in 2014. The results showed that livestock and fertilizer application were the main sources of ammonia emission in Jiangsu province, accounting for 88. 19% of total ammonia emissions of Jiangsu province in 2014. For non-agricultural sources, ammonia from motor vehicle emissions and biomass burning experienced rapid growth trend. In 2014, the average emission intensity of ammonia in Jiangsu province was 4.4t/(km²·a), which was obviously higher than the average ammonia emission intensity in China.
