矿山及周边地区多金属污染土壤修复研究进展

Advances in Research on Remediation of Multi-metal Contaminated Soil in Mine and Surrounding Area

本文阐述了矿区多金属污染土壤植物修复的研究现状及其修复实践。结合国内外多金属污染土壤修复技术与机理研究动态,指出当前相关领域研究中存在的主要问题及未来的研究方向;同时考虑矿山及周边地区重金属污染土壤的不同特点,提出今后的重点是开展分别以植物稳定和植物提取为核心的植物-微生物-化学联合修复机理研究及修复体系建设。

Multi-metal pollution in mine and surrounding area has become one of the most serious environmental problems. The research progress and field practice of phytoremediation of multi-metal contaminated soil were introduced in this paper. On the grounds of the domestic and overseas research trends of the remediation technology and mechanism, key issues on current research as well as the future study on remediation of multi-metal polluted soil were discussed. This paper also pointed out that mechanism study and system establishment for plant-microbe-chemistry integrated remediation technology （based on phytoextraction and phytostabilization respectively） was imperatively needed in view of the diverse characteristics of heavy metal contaminated soils in mine and surrounding area.
