Abstract:
Addressing mining-induced challenges in geological environments is currently a priority for ecosystem conservation and restoration. A prerequisite for formulating effective conservation and restoration strategic planning is to thoroughly ascertain the ecological status and challenges. Based on high-resolution remote sensing image data from 2020 and 2021, and field investigations, this study dynamically monitored the geological environments in mines in west-central Inner Mongolia. The results indicate that in 2021, mining activities in west-central Inner Mongolia led to an additional 3 380.91 hm
2 of destroyed land, while the newly restored and managed area reached 1 801.31 hm
2, suggesting an overall imbalance between mining and management. This study analyzed the status and challenges of geological environments in mines from the perspectives of the spatial distribution and type of destroyed land, mineral species, and restoration and management. Furthermore, this study proposed recommendations for subsequent remote sensing monitoring, restoration, and management of geological environments in mines. Overall, the results and recommendations of this study can serve as a reference for local ecological environment restoration and mineral resource planning.
