Abstract: The amount of anthropogenic ammonia emissions in Jiangsu Zhejiang Shanghai District for the year of 1990 has been calculated. The results of the calculation show that the application of chemical fetilizers, the raising of livestock and the consumption of fuels are the major anthropogenic emission sources of ammonia in this district. The total amount of anthropogenic ammonia emission of the district in 1990 was 769.30 kt, of which livestock accounted for 30.0%, chemical fertilizer 25.0% and fuel consumption 25.8%. The strength of ammonia emission of this district in 1990\ was 3.65 t per square kilometer and 6.26 kg per capita.
