The invention discloses a three-dimensional ship complex space curved surface modeling automatic generation method, which comprises the following steps of: analyzing spatial characteristic lines of a three-dimensional complex space curved surface into spatial geometric curves, and calculating all intersection points among the spatial geometric curves; cutting the space curve into a plurality of arc sections; creating an intersection point-arc section set; searching a space grid strict loop to obtain a loop-intersection-segmental arc set; unavailable arc sections and intersection points are removed; searching a space grid relaxation loop to obtain a'relaxation loop-intersection-segmental arc 'set; updating the'loop-intersection-segmental arc' set; for the "loop-intersection-segmental arc" set, generating curved surface patches of each grid loop by using a skin method, and splicing the curved surface patches to obtain a required spatial curved surface; a grid surface which can be lost by a previous algorithm ca
