Abstract: Focusing on the relationship between urban rail transit and airport economic zone, the role of urban rail transit in promoting the attraction between airport economic regions is analyzed, in order to promote the integration of "AirportIndustryCity" and support the airport economic zone development. On this basis, the layout model of urban rail transit in airport economic zone is put forward, i.e. the concept of "radial layout of express lines + series extension of main lines + connection of secondary lines + density layout of lines in blank areas". Taking the layout of rail transit network in Xi'an Airport Economic Demonstration Zone as an example, the analysis method and application of the layout model is demonstrated.
