The invention relates to a ground feature change monitoring method based on a high-resolution remote sensing image, and the method comprises the steps: obtaining two high-resolution remote sensing images with different time phases before and after the change of a ground feature, respectively recording the high-resolution remote sensing images as a first image and a second image, and carrying out the registration of the first image and the second image; performing radiation normalization processing on the second image by taking the first image as a reference; obtaining change difference valuesof all pixels in the first image on two time phases; identifying shadow pixels in the first image and the second image; and performing object-oriented change region extraction on the first image and the second image according to the change difference value and the shadow pixel to obtain a ground feature change monitoring result. According to the method, the change area can be efficiently extractedaccording to the differen
