The invention belongs to the technical field of remote sensing data processing, and particularly relates to a topographic correction method for the surface radiation quantity of a mountainous area, and the method comprises the steps: S10, obtaining plane surface radiation data of the same period, and the plane surface radiation data comprises short-wave radiation data and/or long-wave radiation data of a plane surface; s20, inputting the plane earth surface radiation data into a pre-established mountain area radiation quantity correction model to obtain a mountain area earth surface radiation quantity; wherein the mountainous area radiation quantity correction model is a mathematical model which corrects the radiation quantity of the plane earth surface through a preset radiation correction coefficient and then outputs the radiation quantity of the mountainous area earth surface; the radiation correction coefficient is determined based on the pixel area and the corresponding mountainous area surface area.
