Taking Pingshuo mine as an example, this paper studies land use, cover change in the process of reclaiming in mine area in the methods of survey in fixed places, indoor analysis, investigation and verification of history data. The results show that as a special land-use form, LUCC is drastic. The change of LUCC in the process that the landform is being restructured is reflected by the change of altitude, slope exposure, slope gradient, slope patterns and specific surface area; the change of LUCC in the process that the soil is being restructured is reflected by the change of soil physical character, chemical character, biological character and erosion character; and the change of LUCC in the process that vegetation is being restructured is reflected by the increase of 91 artificial vegetations and the intrusive growth of 95 wild species.
