The method includes: obtaining optical satellite images and synthetic aperture radar satellite images of an area to be monitored in a preset time period; determining a first target region in each optical satellite image, determining a water body type of a pixel in a second target region in the SAR satellite image corresponding to the first target region; determining water body types of pixels in other regions in the optical satellite image, the other regions being regions in the optical satellite image other than the first target region; and determining surface water distribution information of the area to be monitored in the preset time period according to the water body type of the pixel in the second target region and the water body types of the pixels in the other regions.",
