摘要
土壤重金属污染是全球面临的一个亟待解决的环境问题,植物修复对于重金属污染土壤的治理修复具有重要意义。介绍了植物修复的基本概念及主要作用方式,阐述了重金属有效性、植物修复机理等问题以及增强重金属修复作用的措施。最后结合当今土壤污染的具体情况对今后的研究重点进行展望,提出了植物修复技术的发展趋势。
Heavy metal pollution of soil is a pressing global environmental problem. The phytoremediation is of great importance to repair the heavy metal contaminated soil. Basic concept of phytoremediation and the major modes of its action were introduced. The effectiveness of heavy metal and the mechanism of phytoremediation were discussed. Measures to enhance the remediation of heavy metal, future research focuses and its development trend were presented.
