摘　　要：为了探索对矿区耕地损毁程度等级的评价方法体系，为其土地复垦工作提供一定的理论依据。采用Delphi法、层次分析法和模糊数学综合评价法，研究矿区污染耕地损毁程度等级评价方法。构建了污染耕地损毁程度评价指标（包括土壤重金属含量、土壤pH值、田面污染率、灌溉水质、土壤有机质和土壤微生物数量变化度6个指标）及权重系数，并建立了评价模型。并以云南省某金属矿为例，进行矿区污染耕地损毁程度等级评价，结果表明矿区耕地污染损毁程度为中度-重度，即污染耕地的损毁程度偏重，其损毁程度等级偏高，耕地污染损毁等级达到Ⅲ-Ⅳ级。本文可为矿区土地复垦方案编制、受损耕地的复垦措施及复垦方向确定等提供一定的现实指导意义。The purpose of this paper is to explore the method system that Evaluation on the Degree for damaged Cultivated Land of mining area. It provides theoretical basis to land reclamation work. Methods employed include Delphi, analytic hierarchy process （AHP） and fuzzy mathematics. Constructing the method that evaluation on the degree for polluted cultivated land of mining area in Southwest of China. The results indicate： construct- ed the southwest mine pressure of cultivated land damage degree evaluation index system （including of soil pH value, soil heavy metal, land polluted rate, quality of irrigation water, soil organic matter, soil microorganism quantity）; and established the evaluation model. As an example of metal mine in yunnan province, The degree for polluted land is appraised. In the end, the comprehensive evaluation of polluted cultivated land shows that the degree was destructed from relatively serious to very serious, and the grade was destructed from three to four. The method system can provide some practical directions for land reclamation plan-general, reclamation measures and choosing reclamation forward of cultivated land in mining area
