Abstract: Mining industry contributes to economic growth, but inevitably causes environmental damage and produces large amount of wasteland. Therefore, ecological remediation of mine wasteland is an urgent task for the sustainable development of economy and society. This paper introduced the connotation of ecological remediation and reconstruction, and reviewed the research progress on the substrate amelioration, including surface soil cover, physical, chemical, and biological amelioration, and artificial substrate amelioration, and the vegetation reconstruction of mine land, including natural succession model of vegetation, selection of suitable plant species, and significance of vegetation remediation. The development trend of ecological remediation of mine wasteland in the future was also discussed.
