Abstract The mining wasteland reclamation and utilization proposed in the past two years are of great importance for resource-exhausted cities. The comprehensive benefits evaluation of mining wasteland reclamation and utilization in resource-exhausted cities can objectively quantify the effects of land resources utilization. This study adopted the latest survey data in 2013, integrated the traditional classic methods such as Delphi and AHP with the new methods such as remote sensing and GIS, and took the Qiyueshan mining area of Huangshi City as the study area. According to the characteristics of mining wasteland reclamation, this paper deals with the research idea and evaluation method of the comprehensive benefits evaluation of the mining wasteland reclamation and utilization in the resource-exhausted city, which reflect the overall effect and individual indicator changes of mining wasteland before and after reclamation objectively and quantitatively. The results show the good overall effect of the study area's mining wasteland reclamation and utilization, except that the improvement of some monomial index scores is not obvious. Due attention should be paid to the coordinated development of the economic, social, ecological and landscape benefits in future practices.
