植物修复重金属镉污染土壤研究进展

Research Progress on Phytoremediation of Soil Contaminated by Heavy Metal Cadmium

镉作为我国土壤重金属污染的重要污染物之一,对我国的耕地土壤和人类健康造成危害。目前,关于重金属镉污染土壤的修复方法主要有物理、化学、植物修复等,其中植物修复作为一种绿色、安全有效的修复方法,受到研究者的广泛关注。针对不同类型镉富集植物,即粮食作物、油料作物、药用植物和其他作物,分别描述了其对重金属镉污染土壤的修复能力,以期为重金属镉污染土壤的植物修复推广和种植结构调整提供理论参考。

Cadmium,as one of the important pollutants in soil contaminated by heavy metal in China,has caused harm to our arable soil and human health.At present,the remediation methods of soil contaminated by heavy metal cadmium mainly include physical,chemical methods and phytoremediation.Among them,phytoremediation,as a kind of green,safe and effective remediation method,has received extensive attention from researchers.According to different types of cadmium-enriched plants,such as food crops,oil crops,medicinal plants and other plants,this paper described their remediation ability on cadmium contaminated soil,so as to provide theoretical references for the promotion of phytoremediation of cadmium contaminated soil and the planting structure adjustment.
