The invention relates to an air route congestion propagation path tracing method based on transfer entropy, which comprises the following steps: 1) acquiring related data, and establishing a basic information database; 2) extracting flight path data in a research airspace, preprocessing a flight path, and matching the flight path with a standard flight path; 3) calculating the congestion index of each leg in the research airspace; 4) calculating the transfer entropy of the congestion information between the adjacent legs in each time period; 5) judging the transmission direction and size of the congestion of the legs in the airspace according to the difference of the transmission entropies between the adjacent legs; and 6) tracing the route of the route segment congestion propagation in the airspace by using a breadth-first algorithm. The invention provides the method for accurately deducing the congestion propagation path of the air route network, and reference can be provided for a control unit to explore the operation bottleneck and optimize the air route structure in combination with air traffic operation historical data.
