摘要
定量分析了航空器排放对机场环境的影响,基于LTO循环计算了机场2017年间大气污染物排放量,估算了机场污染物损害的货币价值,对污染物浓度进行预测分析。结果表明:2017年间,浦东国际机场LTO循环数为226475次,NOx、CO、HC、SO2的排放量分别为:4460.7t、2235.7t、199.4t、314.9t,NOx排放量最大。2017年机场污染物NOx、HC的排放总货币估值为9893300欧元。除NOx外,机场其他污染物年均排放浓度较小,扩散浓度受排放量和气象因素的综合作用,且风速对排放扩散起决定性作用。
The impact of aircraft emissions on the airport environment was quantitatively analyzed.The air pollutant emissions of the airport during 2017 were calculated based on the LTO cycle.The monetary value of airport pollutant damage was estimated,and the pollutant concentration was predicted and analyzed.The results show that during 2017,the number of LTO cycles in Pudong international airport was 226 475 and the emissions of NO x,CO,HC and SO 2 were 4 460.7 t,2 235.7 t,199.4 t and 314.9 t,respectively.The total currency of NO x and HC emissions from airport pollutants in 2017 was estimated at 9 893 300 Eur.Except for NO x,the annual average contribution concentration of other pollutants in the airport is small,and the diffusion concentration is affected by the combined effects of emissions and meteorological factors,and the wind speed plays a decisive role in emission diffusion.
