摘　　要：以德国奥斯纳布吕克矿区采煤废弃地土壤作为研究对象,分别对矿区内Ibbenbueren、Piesberg、Wellendorf三个主要采煤废弃地进行调查和土壤营养元素的采样分析,运用基于墒权的属性识别模型对采煤废弃地的土壤肥力进行综合评价。评价结果表明:奥斯纳布吕克矿区内采煤废弃地土壤肥力的总体水平较低,呈中等以下水平,采煤废弃地的植被绿化需对土壤进行施肥,提高土壤肥力,补充植物所需的营养元素。Using the soil of mining wasteland near Osnabrueck ,German as research object ,respectively research on mining wasteland in Ibbenbueren ,Piesberg and Wellendorf and analysis of soil nutrients have been done in Osnabrueck mining areas ,and comprehensive evaluation of soil fertility in wastelands has been made by using at‐tribute recognition model based on entropy objective .The evaluation results show that the general level of soil fertility in wastelands of Osnabrueck mining area is low（ below the middle average） ,and it is necessary to fertil‐ize the soil ,improve the soil fertility and supplement the required nutrient element for plant .
