Provided is a method for upgrading pyrolysis oil through seawater electrochemical pretreatment of biomass and use thereof. The method includes: (1) crushing and sieving a biomass raw material to obtain a crushed biomass raw material, adding the crushed biomass raw material to a salt solution and mixing to be uniform to obtain a reactant mixture; performing an electrolytic reaction on the reactant mixture under conditions of stirring and an external voltage of 5-15 V for 2-8 hours to obtain a product mixture; after the electrolytic reaction, subjecting the product mixture to a suction filtration, collecting a filter cake, washing the filter cake and drying to obtain a pretreated biomass, and (2) subjecting the pretreated biomass obtained in step (1) to a pyrolysis reaction at a temperature of 400-600&#xb0; C. for 30-90 minutes in a protective gas atmosphere, and collecting a pyrolysis oil by an organic solvent.
