The invention discloses an autonomous cooperative traffic complexity management method based on a space-time reachable space. The method comprises the following steps: carrying out track prediction based on related data; generating a rasterized space-time reachable space according to the predicted flight path and the aircraft performance; establishing a multi-target autonomous four-dimensional route planning model according to the space-time reachable space; and calculating the four-dimensional flight path of the aircraft by using a multi-aircraft cluster collaborative optimization algorithm based on a hybrid centralized and distributed strategy through a multi-target autonomous four-dimensional flight path planning model. On the basis of considering the intention and the performance of the aircraft, the rasterized space-time reachable space of the horizontal revision of the aircraft is generated according to the predicted flight path, and the multi-target autonomous four-dimensional flight path planning model considering the flight path complexity and the flight efficiency at the same time is constructed; a multi-aircraft flight path planning problem is solved by adopting a multi-aircraft cluster collaborative optimization algorithm based on a hybrid centralized and distributed strategy, and a solution with higher quality can be provided for a tactical flight path planning process aiming at complexity management within reasonable time.
