Abstract: Mining land in a mining centralized zone is directly related to regional land-use security pattern. Wu’an city was took as a case study. TM images maps in 1996 and 2006 as data sources were used and the combined method of remote sensing software ENVI for automatic recognition and manual interpretation was adopted. The matrix of dynamic land-use change extracted by ARC/INFO and changes of land use area showed that the land type with the greatest change rate was mining land. The landscape indices calculated by the software FRAGSTATS3.3 showed that the role mining and industrial landscape elements played in this region was enhanced, the complexity of distribution of all lands was increased, the dispersion and change range of overall landscape pattern were limited, and that the distribution of mining land was centralized closely with that of mineral resources.
