The invention discloses a method for calculating a spatial geometrical relationship of an airspace grid, and belongs to the field of air traffic management. The method comprises the following steps: firstly, carrying out grid recursion division on a target airspace A, and respectively describing by using a matrix and a position code; for each flight in the target airspace, according to different airspace grid units to which each flight flies, describing a traffic track by using a matrix and a position code; then, dividing a target airspace into'point ', 'line' or'surface 'type airspaces; a'point-point 'space geometrical relationship, a'surface-surface' space geometrical relationship, a'line-line 'space geometrical relationship and a'line-surface' space geometrical relationship are respectively formed; and finally, judging different spatial geometric relationships to obtain the position relationships of inclusion, intersection, adjacency, crossing, distance and the like of the airspace, and providing a more in
