摘　　要：针对2018~2019航季年粤港澳大湾区机场群,通过实际滑行时间修正和大气混合层高度对爬升/进近时间的修正,获得飞机主发动机排放因子和区内机场加权排放因子,同时考虑飞机辅助动力装置的排放,建立了区内飞机起飞着陆(LTO)污染排放清单.结果表明,区域内各机场污染物排放因子存在较大差异,主要来源于实际运行时间的修正以及各个机场不同的机型占比,其中NOx、CO、HC、SO2、PM 5类污染物的加权排放因子区内均值分别为17.58,8.60,0.79,1.37,0.15kg.排放量分别为15327.4,8066.7,728.4,1186.1,121.9t,绝大部分来自飞机主发动机排放.研究期内,NOx排放量在年内呈现夏秋季高、冬春季低的变化趋势,其他污染物排放量变化较为平缓.所有污染物在各机场排放量的次序较为一致,香港、广州白云分列前两位.各机型中,区内NOx及SO2主要来自A320排放,所占比例分别为19.5%、17.1%;CO及HC排放占比最大的机型均为A321,分别为25.4%、27.2%;PM排放量占比最大的机型是B738,约为23.1%.For the Guangdong-Hong Kong-Macao Greater Bay Area airport group in the 2018~2019 shipping season,the aircraft main engine emission factor and the weighted airport emission factor in the region were obtained through the correction of the height of the mixed atmosphere to the climb/approach time and the actual taxi time.Meanwhile,considering the emissions of aircraft auxiliary power units,the inventory of aircraft Land take-off(LTO)pollution emissions was listed.The results showed that pollutant emission factors of airports in the region were significantly different,mainly due to the correction of actual operating time and the proportion of different aircraft types in each airport.The mean values of NOx,CO,HC,SO2 and PM weighted emission factors in the region were 17.58,8.60,0.79,1.37 and 0.15kg respectively.The emissions were 15327.4,8066.7,728.4,1186.1,and 121.9t respectively,most of which were from the main engine emissions of the aircraft.During the research,NOx emissions showed a high trend in summer and autumn and low in winter and spring,while changes of CO,HC,SO2 and PM emissions were relatively flat.The order of pollutant emissions from the airports in the area was relatively consistent,with Hong Kong and Guangzhou Baiyun ranking the top two.Among all models,NOx and SO2 mainly came from A320 emissions,accounting for 19.5%and 17.1%respectively;the models with the largest CO and HC emissions were A321,which were 25.4%and 27.2%respectively;the model with the largest proportion of PM emissions is B738,accounting for about 23.1%.
