| 中文摘要: |
| 京津冀地区不合理的肥料和粪便管理造成了大量的氨排放，促进了该地区PM2.5的上升。本研究基于排放因子法和高分辨率活动数据建立了京津冀地区2015—2019年的氨排放清单，阐明了该地区农业源氨排放的总量和来源、时间变化、空间格局以及减排潜力。结果表明： 2015—2019年京津冀地区年均农业源氨排放量为429.1 Gg·a-1，玉米种植、尿素施用和室内圈舍是氨排放的主要来源；农业源氨排放量逐年下降，其中种植业贡献了75%的减少量。京津冀地区农业源氨排放呈现“南高北低”的格局，50%的县（区、市）贡献了80%以上的排放。提高作物氮利用率可以大幅降低种植业的氨排放（57.5%），采用酸性碳酸钙替代饲料中的碳酸钙则可以有效降低畜禽养殖业的氨排放（26%~53%）。 |
| 英文摘要: |
| Improper management of fertilizer and manure in the Beijing-Tianjin-Hebei(BTH) region has produced high level of ammonia (NH3) emissions, which is an important cause of haze in the BTH region. This study inventoried the agricultural NH3 emissions from the BTH region using the emissions factor method and a high-resolution NH3 activity dataset. The total amount, sources and spatiotemporal patterns of NH3 emissions, as well as mitigation potentials for the same, were evaluated. It was concluded that NH3 emissions from agricultural sources in the BTH region were 429.1 Gg·a-1 for the period of 2015-2019, during which maize cultivation, the application of urea, and indoor housing were the main sources of NH3 emissions. However, NH3 emissions from agriculture also decreased year by year during from 2015-2019, and the reduction from cropland emissions accounted for 75% of the total decrease. NH3 emissions from the southern part of the BTH region were higher than those from the northern part, and half of the counties in the region contributed more than 80% of its emissions. Enhancing the efficiency of nitrogen use could greatly reduce NH3 emissions from cropland(by 57.5%), while replacing calcium carbonate in fodder with acidic calcium carbonate could also effectively reduce emissions from livestock(by 26%~53%). |
