摘　　要：该文运用模糊数学与层次分析法相结合对闭矿后的矿区土地复垦生态安全进行评价。将影响矿区土地复垦生态安全的土壤因素、水文因素、地质因素、风因素、矸石山因素、采空区因素以及其他因素作为影响因素的第一层加以考虑,建立数学模型。根据权重及安全性等级的隶属度得到模糊矩阵,进一步求得矿区土地复垦的生态安全度。作者以某关闭矿区为例,进行了复垦土地安全性评价,结果表明该矿区复垦土地的生态安全性较高。该方法对闭矿后矿区土地复垦生态安全评价具有一定的指导意义。Fuzzy mathematics and Analytical Hierarchy Process（AHP） are applied to assess the safety of ecological environment for mine area after closure. Soil, hydrology, geology, wind, waste piles, mined-out areas, and other factors which influence safety of mining area are considered as the first-laying influence factors, then mathematics model is established. According to the weights of the influence factors and the subjection degrees of danger＇s grades, the fuzzy matrix is established. Then the ecological safety degrees of the mine areas can be calculated. Taking some mine area closed as an example. The ecological security of land reclamation is appraised. Result shows that the ecological security degree of mine land reclamation is high. The method can provide some practical directions for ecological environment of mine areas after mine closure.
