Dynamic analysis on LUCC showed that openpit coal mine in the grassland disturbed grassland ecosystem violently. The coverage and proportion of mining operation areas (open stope, stripping area, wastedump area, mine industrial field) increased, while those of the original landscape decreased continuously. The transfer matrix of land use change showed that wastedump had the largest impacts in the mining disturbance, and that the effective reclamation of wastedump areas would slow down the ecoenvironment destruction, as would be of great significance in protecting the fragile grassland ecosystem. Remote sensing monitoring of openpit coal mining in grassland would accurately reflect the dynamics and trend of LUCC, as would provide scientific support for ecological reconstruction in openpit mining area. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
