Dynamic change of land destroy and reclamation on ATB Opencast Coal Mine

10 times remote sensed data(MSS/TM/ETM +/CBERS) from 1976 to 2006 in ATB Opencast Coal Mine were collected to set up classifications and identification of landuse based on remote sensing and interactively interpret the satellite images. The result indicates that the landuse type changed from simple to complicate during the 30 years, which is 4 types in 1976 to 12 types in 2006. A lot of land was destroyed and the total area is up to 2 730.7 hm². Land reclamation began in 1993 and the reclamation area is 687.05 hm² in 2006. Unfortunately, reclamation land degradation took place in several places because of coal waste rock self-burning, which is spreading. Efficient work has to do to deal with the problem.
