首都国际机场飞机排放清单的建立

将基于标准起飞着陆（LTO）循环各阶段工作时间的飞机排放量计算方法加以改进，利用AMDAR资料计算飞机的有效排放高度，进而准确计算出基于逐架飞机的大气污染物排放总量.结果表明，首都国际机场2013年飞机NO_x、CO、HC、SO₂和PM_2.5排放总量分别为7042.1t、3189.9t、295.3t、429.4t和150.4t.与传统的基于LTO循环的方法相比，修正后的首都机场飞机NO_x、CO、HC和SO₂排放增加了23.5%、2.3%、2.1%和18.1%.飞机排放的CO、HC、SO₂和PM_2.5月变化较小，NO_x排放受飞机有效排放高度影响月波动较大.1～2月飞机污染物排放量处于全年最低水平，8月各污染物排放达到峰值.此外，飞机在爬升和滑行/慢车两种模式下污染物排放比例最大，分别占排放总量的37.7%与36.8%.

Establishment of aircraft emission inventory for Beijing Capital International Airport

The calculation method of aviation emissions based on time spent in various modes in LTO cycles was improved. The effective emission height was calculated based on AMDAR data, instead of using the height (915m) proposed by ICAO. Then, the total amount of atmospheric pollutant emissions from aviation was estimated accurately. The total emissions of NO_x, CO, HC, SO₂ and PM_2.5 from aviation in Beijing Capital International Airport (BCIA) were about 7042.1, 3189.9, 295.3, 429.4 and 150.4t, respectively. As compared with the traditional method based on LTO cycles, the result estimated with the improved method revealed that emissions of NO_x, CO, HC and SO₂ had increased by 23.5%, 2.3%, 2.1% and 18.1%, severally. Monthly emissions of CO, HC, SO₂ and PM_2.5 from aircraft in BCIA presented a relatively steady trend, but NO_x was fluctuated on a large scale. Emissions from aviation were lower in January to February; and monthly emission was peaked in August. Moreover, as for different operation modes, the climbing and taxiing course were found with the largest emission. Approximately 37.7% and 36.8% of the total aircraft emissions were produced in climbing and taxiing, respectively.
