摘　　要：以平朔矿区为例,采用野外定点调查、室内分析、历史资料查证等相结合的方法,研究了黄土区大型露天矿生态重建中的土地利用/覆被变化。结果表明:矿区土地作为一种特殊的土地利用形式,土地利用/覆被变化异常剧烈,其中,地貌重塑过程中的土地利用/覆被变化主要体现在海拔高度、坡向、坡度、坡型、比表面积的变化;土壤重构过程中的土地利用/覆被变化主要体现在土壤物理性状、化学性状、生物性状及侵蚀性状发生变化;植被重建过程中的土地利用/覆被变化主要体现在91种人工植被的增加和95种野生植被的侵入。Taking Pingshuo mine as an example,the paper studied land use/cover change during the process of reclaiming in mine area with the methods binding field pointing survey,analyzing at room,investigating and verifying history data together.The results showed that as a special land-use form, the land use /cover change is unconventionally drastical,Land use /cover change in the course of landform rehabilitation mostly incarnate in the changes of altitude, slope direction, slope degree, slope patterns and ratio surface area;that change during soil reconstruction in physical character, chemical character,bilogical character and erosion.And that change during rehabilitation of vegetation mostly in the increasing of 91 artificial vegetation and of 95 wild species vegetation.
