A method for measuring surface temperature of a turbine blade includes following steps: step 1: cleaning a turbine blade and blowing dry; step 2: firstly, preparing a NiCrAlY (nickel-chromium-aluminum-yttrium) buffer layer and then preparing an YSZ (yttria-stabilized zirconia) insulating layer; step 3, preparing alumina sol; step 4, preparing an alumina insulating layer; step 5, preparing a strip-shaped platinum electrode layer; step 6, preparing a platinum-filled lead wire; step 7: firstly, connecting a platinum wire to a surface of a tail end of the strip-shaped platinum electrode layer, and then connecting a nickel-chromium alloy wire to a tenon end of the turbine blade; step 8, preparing alumina protective layers; and step 9, connecting two cold junctions of a thermocouple with a data collector.
