The invention discloses a super-hydrophobic anti-icing surface and a preparation method thereof, the super-hydrophobic anti-icing surface is provided with a multi-stage and multi-scale cylindrical structure array, and a layer of cluster structure composed of nanoparticles is deposited on the cylindrical structure array. The specific method for preparing the super-hydrophobic anti-icing surface comprises the steps that a to-be-machined material is cleaned, a femtosecond laser machining light path is adopted, and a femtosecond laser focusing point on the surface of the to-be-machined material is obtained; selecting a processing area of a to-be-processed material, setting processing parameters, and controlling femtosecond laser to respectively carry out X-direction and Y-direction laser scanning processing on the surface of the to-be-processed material with the focusing focus, so as to obtain a surface with a multi-stage multi-scale cylindrical structure array; and carrying out chemical modification on the surfa
