摘　　要：国际民航组织规定飞机的标准起降循环(LTO)为滑行、起飞、爬升和进近(不包括巡航阶段)4个阶段,而对机场污染产生影响的主要在起飞和降落阶段。为了计算的可行性,首先简化飞机在机场起飞降落的活动路线,分阶段计算出4个阶段对总的污染排放浓度的贡献;然后计算得出整个民航机场飞机起降循环过程的污染物扩散模型。基于此模型,用MATLAB软件对飞机在机场起飞降落过程中排放的NOx扩散分布进行仿真。ICAO's standard provide that Landing and Take-off cycle(LTO)is taxiing,takeoff,climb and approach(not including the cruise),The pollutants mainly generated by the aircraft are emitted during the process of LTO at the airport.For calculating them feasibly,firstly simplify the aircraft's paths of Landing and Take-off in the airport and calculate emission concentration contributing to the total pollution in the four stages,then get the entire pollutant dispersion of LTO cycle in aircraft civil aviation airport,Based on the model of pollutant dispersion,diffusion of the emitted from the LTO process is simulated by MATLAB software.
