Abstract:The development of mineral resources has driven economic growth, but extensive mining practices have led to ecological and environmental issues. The types, distribution characteristics, mining activities, current land use, and the impact of "three zones and three lines" on 815 historical legacy mine plots have been introduced. Ecological and environmental problems, such as mine geological hazards, land resource degradation in mining areas, and damage to regional groundwater systems have been analyzed. The mining ecological restoration methods and challenges encountered during the process have been summarized, and ecological restoration recommendations have been put forward. It will provide support for ecological restoration efforts and serve as a reference for the restoration of historical legacy mines in Qingdao city.
