| Abstract: | Taking Shenfu Dongsheng mine in north of Yulin Shenmu County，Shanxi Province as a study case，and with the support of ENVI software，Landsat ETM image was used to analyze the spectral characteristics of the image and its value of NDVI，NDBI，NDWI. and this image was transformed with tasseled cap to determine the threshold value for different lands and build a decision tree.Then，the classification results were obtained and the role of decision tree in remote sensing data classification was evaluated. |
