The invention provides a frequency spectrum scanning method and a system. The frequency spectrum scanning method comprises a step of receiving geographical location information or car-mounted terminal field intensity information of transportation facilities sent by the transportation facilities, and a step of determining whether the transportation facilities enter or leave access range of a base station or not according to the position and the access range of the base station and the geographical location information of the transportation facilities or received car-mounted terminal field intensity information. If the transportation facilities enter the access range of the base station, the base station is ordered to stop frequency spectrum scanning and provide service for the transportation facilities. If the transportation facilities leave the access range of the base station, the base station is ordered to enter spare time and begin frequency spectrum scanning. According to the frequency spectrum scanning m
