The invention discloses a power grid bird trouble map drawing method and a system based on a winter visitor migration route and a habitat. In the method, according to a user instruction, a power grid bird trouble map drawing area range is set; winter visitor migration route vector map layer data, winter visitor habitat (such as a water area, a wetland, a farm land, a village and a small town) vector map layer data, winter visitor habitat surrounding line tower coordinates and bird trouble happening frequency data are acquired; according to the acquired winter visitor migration route and habitat vector map layer data, GIS buffer analysis is carried out, GIS interpolation analysis is carried out on historical bird trouble fault data, corresponding thematic maps are obtained, the two maps are integrated, and reference bird trouble risk levels are ranked from low to high, and a power grid transmission line bird trouble map is finally generated and outputted. Important reference can be provided for management decision on anti-bird trouble systems such as an anti-bird sting and an anti-bird baffle arranged on the tower of the power grid, bird trouble tripping accidents can be effectively prevented from happening to the transmission line, and economic benefits are high.
