金属矿山废弃地生态恢复技术

Ecological Restoration Technology for Metal Mine Wasteland

金属矿山开采后的废弃地(如尾矿库)表面形成极端的生态环境,需要进行生态恢复。简述了恢复生态学在废弃地治理方面所应用的理论基础,总结了金属矿山废弃地生态恢复技术包括废弃地工程处理、植被恢复、区域生态系统重建等途径,介绍了我国在金属矿山废弃地复垦、重金属污染的植物修复、改良土壤肥力及区域生态系统的恢复和重建等方面所进行的实践,探讨了今后我国金属矿山废弃地生态恢复工作的发展方向。

The surface of the wasteland （such as tailings reservoir） discarded by metal mines after mining can form an extremely worse ecological environment, which needs to be restored. The paper briefly describes the theoretical basis of ecological restoration that is used in the harnessing of the discarded land, summarizes the ecological restoration technology for metal mines including the engineering treatment, vegetation restoration and reconstruction of regional eco - environment system, presents the practice in China in land reclamation, rehabilitation of heavy metal - polluted vegetation, improvement of soil fertility and restoration and rebuilding of regional ecological system in the wasteland of metal mines, and discusses the trend of the ecological restoration of metal mine wasteland in China.
