摘要
对重庆主城区畜禽养殖业氨(NH3)排放因子进行了本地化修正,估算了农业源NH3排放量。主城区农业源年排放NH38 482 t,其中化肥施用NH3排放量最大,占总排放量的66.7%;畜牧养殖业占26.3%;农作物释放占6.9%。巴南区农业源NH3排放量最大,占主城区排放总量的41%,渝中区为零排放。主城区农业源NH3排放强度为1 552.1kg/km2,大渡口区排放强度最高。主城区畜禽养殖业NH3排放比例低于全国平均水平,化肥施用NH3排放比例高于全国平均水平,但与全国农业源NH3排放结构类似。
Local ammonia（ NH3 ） emission factors of Livestock and poultry breeding in Chongqing urban city is revised and NH3 emission from agricultural sources is calculated. NH3 emission amount from agricultural sources is 8 482 tons every year in urban city. NH3 emission from chemical fertilizer application, which is the largest contributor, takes account for 67%. NH3 emission from livestock and poultry breeding takes account for 26%; crop emission takes account for 6. 9%. NH3 emission in Banan district is the most, which takes account for 41% of total NH3 emission. Yuzhong district has no NH3 emission from agricultural sources. NH3 emission intensity is 1 552. 1 kg/km2 in urban city, NH3 intensity in Dadukou district is the most. Proportion of NH3 from livestock and poultry breeding is higher than the national average proportion, proportion of NH3 emission from chemical fertilizer application is lower than the national average proportion, but structure of agricultural NH3 emission is similar to the national＇ s.
