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, CO, SO, 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 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.
本调查基于国际民用航空组织的标准排放模型，收集了京津冀机场群9个机场的实际飞行状况，充分考虑了大气混合层高度的影响，并采用美国环境保护局的方法对运营时间进行修正，以准确估算2018—2019航运季（364天）京津冀机场群飞机起降周期（LTO）的空气污染物排放清单。结果表明，2018—2019季京津冀机场群LTO周期内NO、CO、SO、HC和PM的排放总量分别为10720.5、3972.2、407.8、508.0和53.7吨。其中，冬春季节排放量分别为4290.2、1646.7、168.3、220.1和22.4吨；夏秋季节排放量分别为6430.3、2325.5、239.5、287.9和31.3吨。从空间分布来看，北京首都机场是该机场群中空气污染物排放量最大的机场。从时间分布来看，最高峰出现在07:00—08:00，12:00—20:00有中高水平排放，21:00之后排放量相对较低。飞机在LTO周期内排放NO和CO较多，PM排放量占比最少。不同工作模式下不同污染物的排放差异显著。在机场群所有飞机中，B777单架LTO污染物排放量最大，B737最小，B787单架LTO循环HC排放量最低。
