摘　　要：我国露天矿土地复垦方向主要为农用地,通过合理的土地适宜性评价方法规划复垦土地的利用方向对实现复垦土地的高效集约利用,防止土地二次退化具有重要指导意义。该文综合考虑露天矿土地适宜性评价对象的预测性、动态性与生态脆弱性等特点,根据预测土地破坏类型与程度以及重塑地貌特征,将辽宁省鞍山市鞍钢胡家庙子铁矿待复垦土地划分为采矿区边坡、排土场边坡、排土场平台三个评价单元,选取主要限制因素,通过极限分析法对各评价单元进行农业利用评价,结果表明采矿场边坡与排土场边坡的复垦方向为林地与草地;排土场平台的复垦方向为园地、林地、草地以及过渡性林地、草地与最终耕地相结合。Reclamation targets in China are mostly agricultural land.In order to make the reclaimed agricultural land develop in the sustainable way,three properties(predictability,dynamic and ecological vulnerability)of land evaluation targets were considered.The land reclamation evaluation unities in Angang Hujiamiaozi iron ore area were divided into three classes:open cast side-slope,dump slope and dump flat.Five limiting factors were chosen in limit analysis method. The results showed that the land will be reclaimed to woodland,grassland,and farmland in a long time.
