中文摘要 基于国际民航组织（ICAO）标准排放模型，调查搜集京津冀机场群9个机场实际航班情况，充分考虑了大气混合层高度的影响，采用EPA方法修正运行时间，精确估算了2018~2019航季年（364 d）京津冀机场群飞机起飞着陆循环（LTO）大气污染物排放清单.结果表明，2018~2019航季年京津冀机场群飞机LTO循环NO_x、CO、SO₂、HC和PM排放总量分别为10720.5、3972.2、407.8、508.0和53.7 t.其中，冬春航季排放量分别为4290.2、1646.7、168.3、220.1和22.4 t；夏秋航季排放量分别为6430.3、2325.5、239.5、287.9和31.3 t.从空间分布来看，北京首都机场是该机场群大气污染物排放量最多的机场.从时间分布来看，07：00~08：00处于排放量最高峰，12：00~20：00处于中等偏高排放水平，21：00之后排放量相对较低.飞机在LTO循环中NO_x和CO排放量较多，PM排放量最少.各污染物不同工作模式下的排放情况差异明显.在该机场群起降所有机型中，B777单位LTO循环排放污染物最多，B737最少，B787单位LTO循环排放HC最低. 英文摘要 Based on the International Civil Aviation Organization's standard emission model, this survey collected the actual flight conditions of the nine airports in the Beijing-Tianjin-Hebei airport group, fully considered the impact of the height of the atmospheric mixed layer, and revised the operating time using the US Environmental Protection Agency method to accurately estimate the 2018-2019 shipping season (364 days) landing and take-off cycle (LTO) air pollutant emissions list for Beijing-Tianjin-Hebei airport group aircraft. The results show that the total emissions of NO_x, CO, SO₂, HC, and PM in the LTO cycle of the Beijing-Tianjin-Hebei airport group in the 2018-2019 season are 10720.5, 3972.2, 407.8, 508.0, and 53.7 t, respectively. Within these, the winter and spring season emissions are 4290.2, 1646.7, 168.3, 220.1, and 22.4 t, respectively; and the summer and autumn season emissions are 6430.3, 2325.5, 239.5, 287.9, and 31.3 t, respectively. From the perspective of spatial distribution, Beijing Capital Airport is the airport in the group with the largest amount of air pollutants discharged. Regarding time distribution, the highest peak is at 07:00-08:00, there is a medium-high emission level from 12:00-20:00, and the emissions are relatively low after 21:00. The aircraft emit more NO_x and CO in the LTO cycle, with PM accounting for the least amount of emissions. The discharges of different pollutants under different working modes are significantly different. Of all the aircraft in the airport group, the B777 unit LTO discharges the most pollutants, that of the B737 is the least, and the B787 unit LTO circulation HC is the lowest.
