2017年合肥市农业源氨排放清单OACSCD
An ammonia emissions inventory for agricultural sources in Hefei, China
大气氨是形成细颗粒物和过量氮沉降的主要前体物,准确编制氨的排放清单对于氨减排策略的制定具有至关重要的指导意义.本研究利用本地化的排放因子,建立了合肥市201 7年高空间分辨率(1公里)的农业源氨排放清单.结果 表明,合肥市2017年农业源氨排放总量为27242.7 t,畜禽源占氨排放总量的54.5％,其中肉鸡和蛋鸡是畜禽养殖源中最主要的氨排放源.空间分布上,合肥市平均的氨排放强度为2.4t km-2,高值主要出现在人口密度较大的区域,其中长丰县和…查看全部>>
A comprehensive agricultural inventory of ammonia emissions for 2017 in Hefei was established on the basis of the specific emission factors and county-level activity data.The emissions over a 1 km × 1 km grid and the associated monthly variations were distributed on the basis of land-use type and meteorological conditions,respectively.The total ammonia emissions were 27,242.7 t in 2017 in Hefei,to which livestock was the top contributor,accounting for 54.5％.…查看全部>>
