The invention relates to an urban riding traffic flow prediction method and system, and the method employs a limit gradient lifting model to predict the traffic flow of shared bicycles in a stable epidemic situation period, and comprises the steps: carrying out the data preprocessing of the station information of shared bicycle stations in a target urban space, and obtaining a data preprocessing result; constructing a Thiessen polygon buffer area with a preset size based on the preprocessed information; meteorological factors, epidemic factors and urban space factors in the Thiessen polygon buffer area are collected and processed to obtain meteorological indexes, epidemic variables and urban space factor indexes; a data set is constructed based on meteorological indexes, epidemic variables and urban space factor indexes, a limit gradient lifting model is input, shared bicycle travel traffic flow prediction is output, and the system is used for implementing the method. Compared with the prior art, the method has the advantages of high prediction speed, high prediction precision, accurate fitting of a nonlinear relation, reflection of spatial heterogeneity and the like.
