摘要
根据氨的不同排放源和排放因子,对贵阳地区2006年氨排放总量进行了估算。结果表明:贵阳地区氨排放总量为72.6kt,其中99.85%来自人为源排放,仅0.15%为自然源排放;在人为源中主要以家畜排放为主,排放量为27.8kt,占总排放量的38.30%;其次为燃煤排放,排放量为23.4kt,占32.26%。贵阳地区氨的排放强度达9.04t/km2,比中国和国外其他地区高,人均排放量达20.57kg/人,虽然与欧洲人均排放量接近,但比其他地区高很多;贵阳地区氨的排放与日本相似,都是以能源和动物排放为主,与中国和国外其他地区均不同,这可能跟贵阳特殊的地理条件和能源结构有关。
According to the ammonia emissions from different sources and emission factors, we have calculated the amount of ammonia emission in 2006,Guiyang. The results showed that the total amount of ammonia emission is 72.6 kt in Guiyang, of which the anthropogenic ammonia emission is 99. 85%, and the natural ammonia emission is 0. 15%. The most important source of anthropogenic ammonia emission is the emission of livestock amounting for 38. 30% ; and the secondary one is the combustion of coal amounting for 32.26%. The intensity of ammonia emission is higher than that in other areas, which reached 9.04 t/km2 in Guiyang. And the ammonia emission is 20.57 kg per capita, which is close to that in Europe but higher than in other areas. The main ammonia emissions are dominated by energy sources and animal sources in Guiyang, similar to the situation in Janpan but different from the other parts of China. This may be related to the special geographical conditions and energy structure
