摘　　要：以德国奥斯纳布吕克地区3种基质类型矿山废弃地作为研究对象,分别对粉煤灰场地、煤矸石山、选煤厂尾矿及煤泥水沉积区3种基质类型的工矿废弃地土壤进行分层采样和理化性质指标分析,对比研究了矿区不同类型工矿废弃地不同基质的自然修复能力以及在进行植被重建时需要修复的土壤理化性质指标。结果显示:以煤矸石为主的场地自然修复能力高于粉煤灰基质和选煤厂尾矿及煤泥水沉积区基质类型。Helmstedt粉煤灰场地周边生长着一些芦苇;煤矸石场地Ibbenbueren和Piesberg山区自然生长着一些灌木;煤泥水沉积区因选煤厂仍在生产,沉积区无植物生长。By taking three types of substrates in abandoned mining areas near Osnabrueck, Germany, stratified sampling of a fly ash field, coal gangue dumps and sludge fields from coal washing and analysis of physicochemical properties were carried out. Comparative research on the natural repair ability of different substrates from abandoned mining areas and the physicochemical properties during revegetation was conducted. The results show the natural repair ability of fly ash substrate is better than that of coal gangue and sludge substrates. At Helmstedt fly ash field reeds grows, at Ibbenbueren and Piesberg fields consisting of coal gangue natural growth of some shrubs was possible and at the sludge from coal washing, no plant growth was visible, since the coal washery was still in production.
