| Abstract: | TM remote sensing images was comprehensively processed.Its mean reflectance characteristics and the structural characteristics of spectra have been analyzed using the spectral curve difference between the sandy land and its background features.An information model has been established,which is suitable for information drawn from desertified land.examples show that its extraction accuracy is 86.733%. |
