重金属污染土壤修复技术研究的现状与展望一、概述随着工业化的快速发展和城市化进程的加速，重金属污染已成为全球范围内日益严重的环境问题。重金属，如铅、汞、镉、铬等，因其不易降解和生物累积性，对生态环境和人体健康构成严重威胁。重金属污染土壤不仅破坏了土壤结构，降低了土壤肥力，还可能通过食物链进入人体，导致各种健康问题。重金属污染土壤的修复技术研究具有重大的现实意义和紧迫性。重金属污染土壤修随着农业的发展和农业生产的现代化，以及盲目的认为土壤是一个具有无限净化容量的处理系统，忽视土壤的环境承载能力，而过量施用劣质化肥农药，造成土壤中重金属污染日益加重。土壤重金属来源广泛，包括采矿、冶金、金属加工、化工、废电池处理、电子制革和塑

1、植物修复技术。这是一种通过自然生长和遗传作用来培育植物对受重金属污染的土壤进行修复的技术。根据机理和作用过程的不同， 此修复技术又可分为植物提取、植物稳定和植物挥发三种类型。⑴植物提取。用重金属超积累ti gong zhong jin shu wu ran tu rang xiu fu ji shu yan jiu de xian zhuang yu zhan wang wen dang mian fei xia zai ，zhai yao ：ying yong sheng tai xue bao 2 002 nian 6 yue di 1 3 juan di 6 qi C H I N E S E J O U R N A L O F A P P L I E D E C O L O G Y , J u n " .

最后，在现有研究分析的基础上，对今后土壤重金属植物修复技术的发展方向提出了几点展望，以期为今后农田土壤重金属污染植物修复工作提多环芳烃（ti gong zhong jin shu wu ran tu rang xiu fu ji shu xian zhuang yu zhan wang wen dang mian fei xia zai ，zhai yao ：zhong jin shu wu ran tu rang xiu fu ji shu xian zhuang yu zhan wang wang xiang jian rang zhong de cun zai xing tai ，reng chi liu zai tu rang zhong 。er qie tu rang hen nan hui "
