【摘要】 稀土是重要战略资源之一,而江西是我国稀土矿储量大省之一。南方离子型稀土矿历经3代不同开采技术,造成土壤酸化、肥力流失、重金属污染、浸矿剂残留、水土流失等污染现状。本文在探讨污染成因的基础上,对矿山土壤修复的物理、化学、生物技术的研究进展进行了归纳总结,并由此探讨矿山土壤修复要解决的关键因素。稀土矿山植被恢复方法中植物修复优势种的筛选是重点,并针对矿山复绿的技术提出未来的研究发展方向。更多还原

【Abstract】 Rare earth is one of the important strategic resources, and Jiangxi is one of the provinces with large rare earth reserves in China. After three generations of different mining technologies, ion type rare earth mine in South China has caused soil acidification, fertility loss, heavy metal pollution, leaching agent residue, soil erosion and other pollution status. On the basis of discussing the causes of pollution, this paper summarizes the research progress of physical, chemical and biological technology of mine soil remediation, and discusses the key factors to be solved in mine soil remediation. The selection of dominant species in vegetation restoration of rare earth mine is the key point. The feasible research direction of mine greening technology is put forward.更多还原
