The invention discloses an air traffic flow chaos prediction method and system, a storage medium and a terminal. The air traffic flow chaos prediction method comprises the following steps: constructing an air traffic flow chaos time sequence prediction model; judging whether the air traffic flow has a chaotic characteristic or not; if yes, carrying out normalization processing on the air traffic flow time sequence; according to the air traffic flow time sequence after normalization processing, phase-space reconstruction parameter delay time and embedding dimension are determined; performing phase-space reconstruction on the air traffic flow time sequence after normalization processing by using the determined delay time and the embedding dimension; and inputting the air traffic flow time sequence after phase-space reconstruction into the constructed air traffic flow chaotic time sequence prediction model for prediction. The model is verified through actual traffic flow data, and compared with a traditional method, the method has better prediction precision and prediction speed for the air traffic flow time sequence.
