摘　　要：根据中国畜禽、氮氨肥施用和生产及人口数量和相应的排放因子，计算了全国氨的排放量、排放强度地理分布和历年的排放量．结果表明，１９９１年全国氨的排放总量为８９１．８万ｔ，其中畜禽、氨肥施用、人粪便与氮肥生产的排氨量分别为６４％、１８％、１７％和１％．氨的排放强度最大的地区在中东部和四川的成渝地区．全国平均氨排放强度为０．９ｋｇ（ＮＨ３）／（ｋｍ２·ａ）．此值小于欧洲的未包括人排放的排放强度１．１ｋｇ（ＮＨ３）／（ｋｍ２·ａ）．The anthropogenic emissions of ammonia in China were calculated based on the number of livestock, poultry, fertilizer application and production and human beings. Results show that the emissions of ammonisa reach 8920 kt in 1991, among which NH 3 emission from animals, nitrogen fertilizer application and human beings and fertilizer production account for 64%, 18%, 17% and 1% respectively. The emission intensity of geographical distribution and emission trends were also estimated.
