Research progress in phytoremediation of heavy-metal contaminated soils with high-biomass economic plants

植物修复是重金属污染土壤修复的重要方法之一。利用高生物量经济植物修复重金属污染土壤,能够兼顾生态和经济效益,具有很大的应用前景。本文系统分析了植物修复现状及存在的问题,提出利用高生物量经济植物修复重金属污染土壤的优势,总结了近年来利用高生物量经济植物吸收重金属的研究进展,探讨了改善高生物量经济植物修复重金属污染土壤效率的方法,以期为提高植物修复经济效益、促进植物修复广泛应用提供参考。

Phytoremediation is one of the important methods for restoring heavy-metal contaminated soils.Using high-biomass economic plants to restore heavy-metal contaminated soils can have both ecological and economic benefits,with great application prospects.Based on the analysis of current situation and existing problems of phytoremediation,we propose the advantages of high-biomass economic plants in contaminated soil remediation,and summarize the recent advances and mechanisms involved in absorbing heavy metals in high-biomass economic plants.Furthermore,the possible methods for improving the remediation efficiency of high-biomass economic plants are also discussed,to provide insights for improving the economic benefits of phytoremediation and promoting its widespread application in the future.
