Different ground features have different spectral values on the remote sensing image. Each type of the rock desertification has its own spectral characteristics . Based on the analysis method of image spectral knowledge, the karst rock - desertification extracting model was built under the direction of the relationship of the spectral value of each type rock desertification and their different bands. The spatial distribution of rock desertification was mapped as important base data support for ecological rehabilitation and management in study area. As a method, the conclusion shows that the spectral feature - based model for extracting rock - desertification information is an effective way on studying the problem of karst rock - desertification because of its feasibile and applicabile.
