The invention discloses a well-ground-air multi-dimensional magnetic anomaly joint inversion method and system. The system comprises a data acquisition module, a grid division module, a matrix generation module, a matrix combination module, an equation construction module and an equation solving module. Firstly, a data acquisition module acquires a total magnetization direction, a ground magnetization direction and observation data of an inversion area; then, the grid division module performs cuboid grid division on the underground space; then, a matrix generation module calculates a ground data kernel matrix, an aeronautical data kernel matrix, a well three-component data kernel matrix and a pre-optimization matrix; then, a matrix combination module combines the three-component data kernel matrixes, the ground data kernel matrixes and the aviation data kernel matrixes in all wells into a total kernel matrix, and combines observation data into a total observation data matrix; afterwards, an equation construct
