The invention belongs to the technical field of steel corrosion resistance and hot-dip galvanizing, and particularly relates to a zinc evaporation pretreatment process for inhibiting selective oxidation of the surface of a high-strength steel plate. According to the process, before continuous annealing, a Zn thin film capable of preventing selective oxidation of the steel-substrate surface is evaporated on the surface of the high-strength steel plate in a vacuum state, and selective oxidation is prevented. The Zn thin film is mainly formed in the mode that pure Zn is heated to a certain temperature, and the Zn is evaporated and condensed to generate metal Zn to cover the surface of a substrate. The Zn thin film has good film-substrate bonding strength. By adopting the process provided by the invention, the Zn thin film is evaporated on the surface of the steel plate, the portion, on the surface of the steel plate, of the substrate is inhibited from selective oxidation in the annealing process, and the defect of skip plating is overcome.
