摘　　要：土壤铅污染已成为严重的环境问题,重金属铅在土壤中分布广泛且具有积累性,能够通过食物链富集而危害人体健康,发展有效且环境友好的土壤铅污染修复技术已成为当前的研究热点。文章综述了土壤铅污染的来源、现状及危害,简要介绍了修复土壤铅污染的新方法——植物修复技术及其相关的超富集植物。同时,探讨了超富集植物修复土壤铅污染的现状及应用状况,为进一步利用植物修复技术治理土壤重金属污染提供理论依据。最后,指出目前超富集植物萃取土壤重金属技术的不足,并对今后超富集植物修复技术予以展望。Soil lead pollution induces serious environmental problems. Heavy metal lead is widely distributed and cumulative in the soil, which can be enriched into body through the food chain and subsequently endangers human health. Therefore, the improvement of soil lead pollution through phytoremediation is becoming of concern. This paper summarizes the source the current situation and the harm of soil lead pollution, and briefly introduces the phytoremediation and hyperaccumulation plants. We simultaneously discuss the present research situation in the control of soil lead pollution, which can provide further information for controlling soil lead pollution based on phytoremediation technology. This paper points out the problems existing in the hyperaccumulator extraction technology of soil heavy metals, and gives prospect of the future study on phytoremediation of hyperaccumulator.
