    内蒙古中西部矿山地质环境遥感调查

    Remote sensing survey of geological environments in mines in west-central Inner Mongolia

    • 摘要: 治理矿山开采诱发的地质环境问题是当前生态系统保护和修复的重点方向,制定保护和修复战略规划前必须摸清生态环境现状与问题。基于2020年与2021年高分辨率遥感影像数据,结合实地调查,对内蒙古中西部矿山地质环境进行动态监测。结果显示,内蒙古中西部2021年采矿新增损毁土地面积达3 380.91 hm2,新增矿山恢复治理面积达1 801.31 hm2,总体上未实现“边开采,边治理”平衡。从损毁土地空间分布、损毁土地类型、开采矿种、恢复治理等角度分析矿山地质环境现状与问题,并依此提出下一步矿山地质环境遥感监测与恢复治理的建议。调查结果和建议可为当地开展矿山生态环境修复工作、矿产资源规划提供参考依据。

       

      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 hm2 of destroyed land, while the newly restored and managed area reached 1 801.31 hm2, 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.
