重金属Cd污染土壤的植物修复研究

Study on Phytoremediation of Heavy Metal Cd-contaminated Soil

土壤重金属污染是当今世界的重要环境问题。重金属Cd易被植物吸收,迁移性强,很难在环境中降解,已对我国部分土地造成严重污染,是当前土壤重金属污染治理的关注对象之一。植物修复绿色无污染,它是目前应用最广的重金属Cd污染治理技术,具有良好的应用前景。本文综述了植物-微生物联合修复、植物-化学联合修复及农艺强化修复的研究进展,为后续研究奠定理论基础。

Soil heavy metal pollution is an important environmental problem in the world today.Heavy metal Cd is easily absorbed by plants,has strong mobility,and is difficult to degrade in the environment,which has caused serious pollution to some land in China,it is one of the concerns of the current soil heavy metal pollution control.Phytoremediation is green and pollution-free,which is currently the most widely used heavy metal Cd pollution control technology and has good application prospects.This paper reviews the research progress of plant-microbe joint remediation,plant-chemical joint remediation and agronomic enhanced remediation,and lays a theoretical foundation for subsequent research.
