摘    要：金属矿产资源开发为我国国民经济建设做出了巨大贡献，但受早期监管无序及开采工艺落后的影响，不仅造成了我国矿产资源的极大浪费，而且引发了日益严重的生态环境问题，特别是废弃矿山土壤重金属污染对人类的生存构成了潜在威胁.文中分析了矿山废弃地的特征和危害，并全面介绍了植物修复技术修复重金属污染土壤的原理、特点、研究应用现状等，针对植物修复技术目前存在的问题及其解决方法进行了相关探讨.

Abstract: Metallic mineral resources development has made a great contribution to China’s national economy. However, exploitation of mineral resources was extremely inefficient accompanied with severe ecological and environmental problems in China due to mismanagement and backward mining technology. Heavy metal pollution in mining wasteland soils is one of the pressing problems for its potential threats to the survival of human being. This paper analyzes the characteristics and potential hazards of mining wasteland based on introducing the working mechanisms, characteristics and current advances in research and application of phytoremediation technologies for reclaim of heavy metal polluted soils. The current challenges and perspectives of phytoremediation technologies are also discussed.
