An aerial seeding bioremediation method for a coal mining subsidence area. The method includes obtaining a topographic map of the coal mining subsidence area; grading the topographic map in terms of ground slopes; determining seeding coefficients of aerial seeding operation according to a grading result of the ground slopes and ground coverage rates of the coal mining subsidence area; determining height adjustment parameters during unmanned aerial vehicle, UAV, aerial seeding; and performing, by a UVA, the aerial seeding operation according the grading result of the ground slopes, the seeding coefficients of the aerial seeding operation, and the height adjustment parameters. A slop grading technical standard of aerial seeding determined by the method of the present disclosure is applicable to complex topography of the coal mining subsidence area and helps with safety of the UVA.
