The invention provides a GIS-based transformer substation site selection method including the steps of obtaining the total investment I < total > of the power transmission and transformation project in the target area; establishing a three-dimensional coordinate system (x, y, z); taking longitude and latitude coordinate data of the target area as (x, y) in a coordinate system; taking the Z axis asthe total cost I total, establishing a mapping from a plane coordinate to the total cost I; using geographic data for converting the plane coordinates and the latitude and longitude coordinates, wherein the site selection area of the transformer substation is a plane coordinate (x, y), the Z-axis is the total cost, a three-dimensional visual structure model is formed, in which the peak in the model is a point with higher total cost I, and the low ebb is the point where the total cost I is relatively low; the method also includes sorting the cost of the target area according to the total costof the total cost I; scree
