Abstract Research purposes:Intercity rail transit is a new form of rail transit. In order to facilitate the transfer， electromagnetic compatibility between intercity rail transit and the airport navigation facilities is increasedly concerned. By using electromagnetic radiation testing results of a number of recent domestic urban rail transit systems，this paper predictively analyzed the electromagnetic impact of Nanjing一Gaochun intercity DC rail transit on some airport navigation facilities of Nanjing Lukou，and provided the technical basis for the rationality and feasibility of intercity rail transit line selection.

Research conclusions:(1)The electromagnetic radiation generated by train running on Nanjing一Gaochun intercity DC rail transit while it is in tunnel is shielded and will no longer pose a threat to the navigation facilities on board or on the ground.(2)After the lateral attenuation，the component corresponding radar and pointing beacon'.s operating frequency of electromagnetic radiation generated by the train at the tunnel portal decreases sharply. Especially to the ATC secondary radar, the interference component is lower than background values.(3)The conclusions above provide the technical basis for intercity rail transit line selection.

Key words： intercity rail transit navigation facilities;electromagnetic environment
