Based on the ETM multispectral remote sensing image of West Ujimqin Typical Steppe with the resolution of 30 meters on August 2012, this research classified the image date by using several supervised classification methods. And evalu-ated and compared the classification effect and accuracy of each classification method. Aimed at classifying the typical steppe degradation, investigated the merit and demerit of each classification methods, chose the optimized classification method to research degradation of typical steppe. Then used the priori knowledge and the field investigation data to analyze the classifi-cation results, evaluated and compared the classification accuracy through the overall classification accuracy, confusion matrix and Kappa coefficient.
