摘　　要：按照国际民航组织规定的起飞着陆循环过程,简化飞机在机场起飞降落的活动路线,在原有飞机排放污染物排放指数(EI)计算的基础上,再结合飞机起飞降落过程的燃油流量(F),计算出进近、滑行、起飞、爬升四段路线的排放污染强度。基于高斯点源扩散公式,对其进行积分得线源扩散模型,再对线源扩散模型中的参数进行修正,建立了民航机场飞机排放浓度模型。According to ICAO＇ s standard of Landing and Take-off cycle, the aircraft＇ s paths of landing and take-off in airports are simplified. The process to calculate the pollutant emission index （EI） of aircraft emissions has been got in the original work ,combined with fuel flow（F） during process of the aircraft landing and take-off,the e- mission intensities of approach, taxi, take-off and climb are calculated. Based on the Gaussian point source dif- fusion formulation, the line source diffusion model is integrated, with correction of the parameters the distribu- tion model of aircraft emission in the airport is established.
