The invention discloses a short-term subway pull-in passenger flow volume prediction method, which comprises the following steps of A, acquiring pull-in passenger flow volume data of a plurality of different stations within a specified time range to obtain an initial pull-in data set; b, acquiring a primary residual sequence of each piece of initial data in the initial pull-in data set; c, acquiring a cubic decomposition subsequence of a primary residual sequence of each piece of initial data in the initial pull-in data set; d, taking all primary decomposition subsequences of the initial data in the obtained initial data set except the first subsequence and a tertiary decomposition subsequence of the initial data as a data set of an LSTM neural network, and training to obtain a trained LSTM neural network; and E, taking the pull-in passenger flow data of the to-be-predicted station in Q days before the to-be-predicted date as initial data, and performing passenger flow prediction by using the trained LSTM neural network. According to the method, the short-term subway pull-in passenger flow volume can be accurately predicted.
