摘　　要：本文综述了植物根茎吸收和富集重金属的机制,探讨了重金属在土壤中的存在形态及其生物有效性,分析了植物根系对重金属离子的吸收途径、转运机制以及根茎部重金属的累积特性。同时,本文进一步讨论了影响这些过程的环境因素,如土壤pH值、有机质含量、微生物活动等,介绍了以此理论为基础的重金属植物修复技术,并提出了当前研究中存在的问题和未来的研究方向。本综述旨在增进科研人员及相关工作者对植物根茎富集重金属机理的理解,为环境保护和土壤重金属污染治理提供一定的科学依据。In this paper,we summarized the mechanisms of absorption and enrichment of heavy metals in plant roots,explored the morphology and biological effectiveness of heavy metals in soil,and analyzed the absorption pathway of heavy metal ions and the cumulative characteristics of heavy metals in plant roots.Meanwhile,this paper further discusses the environmental factors affecting these processes,such as soil pH,organic matter content,and microbial activities,introduces the heavy metal phytoremediation techniques based on this theory,and proposes the problems existing in the current research and future research directions.The review aims to improve the understanding of researchers and related workers on the mechanism of heavy metal enrichment in plant roots,and provides some scientific basis for environmental protection and soil heavy metal pollution control.
