矿区废弃土地复垦潜力评价方法与应用实例

Evaluation method and its application to the potentiality of wasteland reclamation of China's abandoned mining areas

文章根据实地调查研究 ,筛选出了影响矿区废弃土地复垦潜力的自然和社会经济条件方面的 4类 1 4个亚类因子 ,并划分为 6个等级。运用层次分析法 ,参考专家评分 ,来确定矿区废弃土地复垦综合潜力值的大小及每一级别的值域范围。以河南省平顶山市焦店乡为例 ,阐明了进行矿区废弃地复垦潜力评价的具体过程与方法 ,可为全国矿区废弃地复垦潜力评价及矿区废弃地有效合理利用提供有益参考。

Few researchers have been involved in the study of the potentiality of wasteland reclamation of China's abandoned mining areas in a systematic way. According to field investigations, 14 sub factors in 4 categories including soil (such as soil depth, quality, organic compound content, water content, pH value, harmful elements content etc), topological remolding (such as ground gradient, ground damage degree, difficulties in ground rehabilitation), climate and hydrology (such as average cultivated lands, average net income and regional locational condition), and further dividing into 6 gradations are identified as natural and socioeconomic aspects that influence the potentiality of wasteland reclamation of the abandoned mining areas. The corresponding values and ranges of the potential value and range of each gradation are established by using the hierarchical analysis and expert assessment methods. An application in Jiaodian Village (located at Pingdingshan city in Henan Province) is given to exemplify the detailed process and method for the assessment of the wasteland reclamation potentiality of China's mining areas, which serves as a reference for the potential assessment on the wasteland reclamation of China's mining areas.
