【摘要】 金属矿区及周边土壤重金属污染已成为严重的环境问题之一。重金属污染使土壤质量下降,生态系统退化,同时污染农作物,威胁到人类的健康。目前,修复重金属污染土壤的方法很多,包括物理、化学、生物等方法。其中生物修复法近年来得到了特别的重视,并取得了显著进展。文章全面介绍了目前各种生物修复技术:植物修复、微生物修复以及微生物-植物联合修复,包括修复原理、进展、优缺点等。矿山固体废物和酸性废水导致矿区土壤中富集大量重金属,结合目前生物修复技术及其应用,对金属矿山重金属污染土壤的整体修复提出设想,并进一步指出发展方向:将基因工程引入植物的重金属修复;构建菌根-植物-微生物修复体系,促进土壤重金属污染的生物修复。更多还原

【Abstract】 Heavy metal pollution,which causes soil quality decrease,ecosystem degeneration,crops contamination and influences on human health,has become one of the most serious environmental problems today in mining and the surrounding areas. Recently,bioremediation has attracted special attention and gained remarkable developments. This paper introduced bioremediation technologies,which include phytoremediation,microbial remediation and plant-microbe remediation methods. At the same time,advantages and disadvantages of technology and their future development were reviewed. Solid wastes and acid water caused heavy mental enriched in soil surrounding mine,according to bioremediation and its application,an assumption was made to remedy heavy metal contaminated soils in whole and development trend was predicted including introducing genetic engineering into phytoremediation,constructing remediation system of mycorrhiza,plant and microorganism to promote bioremediation.更多还原
