It is urgent in the time of high speed development of China’s mining industry to research the issue of waste land reclamation of China’s mining areas because of the severe damage of China’s land resources in mining areas and low reclamation ratio (about 10%) of its waste lands. To launch in the whole country the suitability assessment of the waste land reclamation of China’s mining areas can serve as a real time guide for relevant researches because of its basic function in the research of the waste land reclamation of China’s mining areas. According to this function, the thesis divides the waste land resources of China’s mining areas into 25 sub categories of 5 categories on the basis of field investigation and utilization of certain principles. Every type of 25 sub categories is assessed on their suitability for the waste land reclamation, and corresponding ways for the exploitation and utilization of China’s waste land resources are also put forward. These detailed methods can in an efficient way serve as a scientific assessment tool for the evaluation of China’s waste land reclamation, so as to improve the efficiency of China’s waste land reclamation and utilization, and to provide an efficacious reference for relevant policy making.
