The invention discloses a process-oriented air pollution event modeling method. The method comprises the steps of firstly, defining an air pollution event and identifying snapshots of the air pollution event at all moments according to air pollution standards; and then performing modeling on the air pollution event from a process perspective according to a spatial relationship of the same air pollution event snapshots in a continuous time sequence, thereby obtaining an air pollution process-based model. According to the modeling method provided by the invention, time and spatial information of all stages of the air pollution event can be intuitively obtained; association of air pollution events with the surrounding geographic environment and special events can be assistantly comprehended; and guidance is provided for exploring causes for the air pollution event and policies.
