Provided is an identification method of a mud-rock flow emergent region in a remote sensing image. The identification method is characterized by acquiring the high-resolution satellite remote sensing image data: preprocessing the remote sensing image; performing computer automatic identification on the mud-rock flow emergent region in the remote sensing image; performing artificial correction on the mud-rock flow emergent region in the remote sensing image; and performing disaster prediction on the surrounding areas of the mud-rock flow emergent region based on the final identification result. The mud-rock flow generation area is analyzed and extracted through the mud-rock flow identification index, the identification of the mud-rock flow emergent region can be finally realized, the scale and damage degree can be known, and the prediction can be made for the potential impact of the surrounding areas, and the method is a convenient, rapid, low-cost, and effective mud-rock flow emergent region identification.
