Abstract: 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.
