Abstract：Annual emission of ammonia and NOx in the inland of China were calculated based on the numbers of livestock, poultry, human beings, the quantity of fertilizer application and production and fuel consumption. The temporal and spatial distribution of emission intensity of NH3 and NOx were also analyzed. NH3 emission in China changed slowly from 10.6Tg in 1995 to 12.0Tg in 2004, while NOx emission increased quickly from 12.2Tg in 1995 to 20.6Tg in 2004, with a mean increase rate of 68.9%. In 2004, emission from livestock, nitrogen fertilizer application, human beings and fertilizer production accounted for 69.2%, 15.2%, 13.9% and 1.9% of the total NH3 emission, respectively. Emission from coal combustion accounted for about 77.4% of the total NOx emission. The emission from coal combustion accounted for about 77.4% of the total NOx emission. The emission intensity of NH3 and NOx in the middle-east zones were much bigger than that in the west zones of China, due to large numbers of livestock, population and quantity of fuel consumption.
