Object-oriented monitoring of coal mine land use change

摘要

Taking Dongsheng district of Erdos City in Inner Mongolia as the research area, we used the object-oriented classification method to monitor the land use change in recent years. The images of the three periods were classified into vegetation, residential area, water body, the mining area as well as the bare land, of which the accuracy rate has reached 86%. The results were produced by statistically analyzing. From 2006 to 2011, the vegetation was badly damaged, including the expanding residential areas and mining areas. The residential area was constantly expanding between 2011 and 2018, but the total area of the mining area and vegetation cover has not changed much. The area after the mining has been re-greened, which is conducive to the coordinated development of that area.
