矿山废弃地生态环境恢复治理进展

Advances of eco-environmental remediation of mine wasteland

  • 摘要: 矿产资源是我国经济社会发展的重要物质基础,但其开发带来了侵占耕地、破坏生态、污染环境、地质灾害等严重问题,矿山废弃地生态环境恢复越来越受到专家学者和政府部门的重视。对我国矿山资源开发现状及问题、相关政策及修复现状进行了概述,分析了矿山废弃地的特点及生态环境恢复目标。着重介绍了现阶段矿山生态修复涉及的基质改良、生态系统修复手段,并指出各类技术在矿山废弃地生态修复实践中的适用性和优缺点。最后,针对矿山废弃地生态修复存在的投入资金不足、不到位、技术缺乏等问题提出可行性方法,以期为矿山废弃地生态环境修复提供参考。

     

    Abstract: Mineral resources are important material bases to support Chinese social and economic development. On the other hand, mining activities have introduced severe environmental pollution and resulted in serious impacts on the surrounding environment, such as the decrease of cultivated areas, destruction of sensitive ecosystems. Therefore, the eco-environmental restoration of mine wastelands is more and more concerned by experts and government departments. The current status of mineral resources exploitation, environmental problems caused by mining activities, related policy, and current restoration situation were reviewed. Meanwhile, the characteristics and ecological restoration objectives of mine wastelands were analyzed, related substrate modification and eco-system restoration technologies introduced, and the application adaptability and advantages and disadvantages of the technologies pointed out. Finally, some potential solutions were proposed aiming at the problems such as lacking of investment funds and technologies, so as to provided reference for the ecological restoration of mine wastelands in the future.
