The invention discloses a statistical analysis method and a statistical analysis system for city public transportation passenger flow information. The invention belongs to the technical field of intelligent transportation. The system comprises a pre-processing module, a segmentation module, a station matching module, and a displaying module. The pre-processing module is used for eliminating invalid data in card swiping data of City Card. The segmentation module is used for carrying out trip-time segmentation and station segmentation upon the card swiping data of City Card, such that trip-time card swiping data and station card swiping data are obtained. The station matching module matches the data with actual physical stations according to the trip-time card swiping data and the station card swiping data, such that the card swiping data of the actual physical stations is obtained. The displaying module superimposes the card swiping data of the actual physical stations on a city map file, and displays a passenger flow map. According to the invention, station characteristics are identified according to the spatial location relationship between stations and lines; and card swiping data is matched with the stations, such that spatial locations of the card swiping data are obtained. Therefore, data support is provided for city transportation planning.
