重金属污染土壤的植物修复技术研究进展

土壤重金属污染已成为全球性问题。污染土壤的传统治理方法成本高、效率低,并且还给生态环境带来其它危害。植物修复技术因成本较低、易被公众接受且无二次污染等优点越来越受到重视。介绍了植物修复技术的分类及超积累植物的来源、发展、筛选、应用,就植物修复技术的植物资源进行了综述,并对重金属污染土壤的植物修复技术进行了展望。

Research Progress in Phytoremediation of Heavy Metal Pollution in Soil

Heavy metal pollution in soil is a pressing problem to be solved in the the world. There is a high cost and low efficiency for the traditional soil pollution treatment methods, which also destroy the ecological environment. Phytoremediation is more and more taken attention for its low cost, no secondary pollution, and easily accepted by the public. The classification of phytoremediation, source, development, screening and application of hyperaceumulation plants were introduced. The plant source for phytoremediation was reviewed and the phytoremediation of heavy metal pollution in soil was prospected as well.
