【Abstract】 In order to reduce the environmental impact during the operation of the corridor and alleviate the greenhouse effect,the flight level of corridor was optimized by considering two factors including CO₂ emission and contrail formation.Firstly,the mechanism of CO₂ emission and contrail formation was studied,the quantitative calculation of the influence of CO₂ emission and contrail on the greenhouse effect was realized based on the radiative forcing model.Secondly,the unified measurement standard of satisfaction function of corridor optimization model was establishedbased on the multi-objective fuzzy optimization method,in which Dijkstra algorithm was used to solve the model.Finally,the route from Guangzhou Baiyun Airport to Beijing Capital Airport was taken as a case study.The result shows that the optimized corridor could can effectively avoid most areas of the contrail and the total radiative forcing of aircraft flight was reduced by 73%,which reduces the impact on the greenhouse effect.更多还原
