Method for dynamically dividing sector based on airspace traffic characteristics

The invention belongs to the field of air traffic management, and discloses a method for dynamically dividing a sector based on airspace traffic characteristics, which aims to confirm a sector division matched with airspace traffic changes according to airspace traffic change control, so as to realize optimal utilization of airspace resources. The method comprises three aspects, namely airspace information extraction, airspace modeling and sector optimized division algorithm. First, databases such as an airspace topological structure are constructed on basis of airspace static structural information and airspace dynamic information; then, a complicated network model is used for describing an airspace structure through regarding key points as nodes and air routes as sides; third, similarity of associated nodes in the complicated network model is calculated according to airspace dynamic information, a complicated weighing network is established, and an airspace convex cell model is established by utilizing the
