摘要
我国南方离子吸附型稀土矿产资源丰富,近几十年来,无序民采和商业矿采活动给矿区及周边生态环境造成了严重破坏,已极度威胁到当地农产品质量与人体健康安全。目前,寻找合适的矿山土壤与生态修复技术是国内外生态环境领域的研究热点与难点。本文在全面调研和搜集离子吸附型稀土矿相关文献的基础上,阐明了采矿活动引起的生态破坏和环境污染,评价了矿区居民的人体健康风险,总结了土壤修复与植被恢复技术在离子吸附型稀土矿区中的应用进展。最后结合各修复技术特点和场地条件展望了稀土矿区的未来用途,以期改善其恶劣的土壤与生态条件、促进稀土矿区环境与经济的协同发展。
South China is rich in ion-adsorption type rare earth mineral resources.In recent decades,the disorderly civilian and commercial mining activities have caused serious damage to the mining areas and the surrounding ecological environment,which has greatly threatened the quality of local agricultural products and human health.At present,finding suitable soil and ecological restoration technology is a difficult topic and research hotspot in the field of ecological environment at home and abroad.On the basis of comprehensive investigation and collection of literature related to ion-adsorption type rare earth ore(IREO),this paper clarifies the ecological destruction and environmental pollution caused by mining activities,evaluates the human health risks of residents in mining areas,and summarizes the application progress of soil remediation and vegetation restoration technology in IREO.Finally,combined with the characteristics of various remediation technologies and site conditions,this paper looks forward to the future use of IREO mining areas,in order to improve their poor soil and ecological conditions,and promote the coordinated development of the environment and economy in the IREO mining areas.
