The invention relates to an approach flight flow flight plan prediction method for terminal area traffic simulation, which comprises the following steps of: extracting flight path points in a terminal area range from a database, storing the flight path points in a trajectory form according to flight numbers, and cutting the trajectory and separating approach and departure trajectories to form an approach trajectory set gamma; flight flow identification is carried out; an inter-trajectory symmetric one-way large circle distance measurement model is established, and a trajectory similarity matrix is established; according to the approach trajectory set gamma, calculating a height layer composition proportion and a flight model composition proportion of the flight flying over the boundary of the terminal area; according to the flight flow trajectory, identifying to obtain a flight flow center trajectory, and further extracting turning feature points from the center trajectory to realize construction of a planned flight route; counting the flight flow of each flight flow per hour in 24 hours of a day; and predicting a future flight plan. According to the method, the simulation plan making efficiency can be improved, the fidelity of airspace traffic simulation is improved, the credibility of a simulation evaluation result is improved, and the terminal area traffic planning scientificity is improved.
