摘　　要：利用2001年、2005年两期TM影像对平朔矿区的土地利用情况进行了监测,结合矿区开采规划,分析了矿区的土地变化的特征,主要表现在:建设用地与未利用地面积显著增加,耕地呈减少趋势,建设用地的增加是以侵占大量农田为代价的.利用空间马尔柯夫模型对平朔矿区2 0 2 1年土地进行预测并结合矿区规划进行修订,结果表明:研究区内土地利用变化以各类型转化为建设用地的趋势最强,在一定程度上显示了研究区的城市化过程和工矿用地的扩张.The issue base on TM image of 2001and 2005 to conduct investigation of land use situation in Pingshuo opencast mine, analysis the change of land features in the area with mine planning. It can be listed as follow： construction land, uncultivated land increased sharply, arable land decrease apparently, the increase of the construction land was at the cost of encroaching of the arable land. We forecast the land use structure of 2021 with the Markov chain. The results show that the trend that all the other types translated into the construction land appears much more dominantly than any others in the studying region. In the meanwhile, it also indicates that the studying region is in a fast developing stage of urbanization and expanding of the mine to a certain extent.
