摘要
土壤污染是当今世界面临的主要环境问题之一.传统的污染土壤的物理化学治理技术具有技术要求和经济成本高,严重破坏土壤结构等缺点,不适于低浓度、大范围污染土壤的治理及应用.与之相比较,植物修复以其修复成本低、无二次污染等独特的优势正受到全世界的普遍关注和重视,并成为环境污染治理研究领域的一个前沿性课题.就我国土壤重金属污染现状与危害、植物修复的原理与优缺点及其研究展望作一简述.
Soil pollution has been considered as one of the main environmental problems through the world nowadays. Physio-chemical techniques, which with the disadvantages of high costs, strict technical demands, and serious damage on soil texture, has not been applied to heavy metal contaminated soil on a large scale, especially to slightly contaminated soils. While, phytoremediation with the advantages of low cost and non-diauxic pollution has become a perspective technology for remedying contaminated soils. This paper reviewed the situation of soil contaminated by heavy metal in China, principles, advantages and disadvantages, and perspectives of phytoremediation.
