Abstract：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.
