向土壤中添加螯合剂促进植物对重金属的吸收是目前一项比较有发展前景的土壤修复技术。但由于Pb在土壤中的的存在形态不一，导致植物有效性较低，利用植物对土壤中铅的修复效率十分有限，所以向土壤中施加一定量的螯合剂有助于植物对铅的吸收。如今螯合诱导技术已经成为一个国际热点和发展的趋势。该文主要介绍了螯合剂种类的划分以及螯合诱导技术强化植物修复铅污染土壤的应用现状，综述了Pb污染土壤螯合诱导强化植物修复技术的研究进展，最后对螯合剂在植物修复重金属污染土壤应用中存在的问题进行了分析讨论，并对未来螯合诱导技术今后的发展方向进行了探讨与展望。

Chelating agent is added to the soil to promote plant uptake of heavy metals is a relatively prom-ising soil remediation technologies. However,due to the presence of Pb varies forms in the soil,resulting in lower plant availability,utilization efficiency of phytoremediation of lead in soil is very limited,so a certain amount chelator applied to the soil helps plants absorb lead.Today,technology has become a chelate-in-duced trend in international hot spots and development. This paper describes the types of chelating agents induce division and chelation technology application status enhanced phytoremediation of lead contaminated soil,lead pollution in soil were reviewed chelating induced to strengthen the research progress of phytoreme-diation technology. In addition gives a good view of chelate-induced phytoremediation. The problems about chelate-induced are discussed,and the future directions research are briefly stated.
