The invention discloses a heat-resistant steel aging detection method under surface characteristic interference and a storage medium. The method comprises the following steps: acquiring a sample of which the surface is treated, performing LIBS detection on the sample to obtain sample spectral data and construct a data set, and establishing an aging detection model by using the data set; the method comprises the following steps: acquiring a to-be-detected object with an untreated surface, and performing LIBS detection on a plurality of measurement points of the to-be-detected object to obtain laser spectrum chromatography data; carrying out representative spectrum screening, feature selection and intensity correction processing on the chromatography data to obtain corrected spectrum data; and performing aging detection on the corrected spectral data by using a heat-resistant steel aging detection model. According to the method, the representative spectral information of the matrix of the heat-resistant steel u
