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

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.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。.
