摘　　要：矿区土地的适宜性评价研究是复垦复绿研究的基础。为此,结合河北省矿区地形实际情况并参考评价单元的划分依据,将矿区的复垦复绿土地划分为塌陷区、挖损区、压占区和矿石加工及影响区4个评价单元,又选取坡度、表土质地、有效土层厚度、灌溉条件、排水条件和有机质含量6个指标作为评价因子,运用主成分分析法确定权重,采取指数和法计算综合指数,对不同评价单元进行适宜性评价。结果表明,塌陷区的土地利用方向为耕地和林地;挖损区的土地利用方向为公园用地;压占区的土地利用方向为牧业和林地;矿石加工及影响区的土地利用方向为耕地。The suitability evaluation of the waste land reclamation of mining areas is the basic function in the research of the waste land reclamation of mining areas.With considering the terrain situation of Hebei Province and division basis of the evaluation unit,the mine area is divided into four evaluation unit： subsidence area,digging loss area,pressure occupy area and ore process or influence area,selection slope,surface soil texture,effective thickness of soil layer,irrigation condition,drainage condition and organic matter content for the evaluation factor.using the principal component analysis to fix on the weight of the indexes and summing the grades of each evaluation unit to calculate the comprehensive index,to evaluate suitability in evaluation unit.The result shows that subsidence area land can use for infield and woodland;digging loss area land can use for park;pressure occupy orea land can use for pasture and field;ore process or influence area land can use for infield.
