摘要
随着工农业的发展,重金属Cd污染也日益严重,为了减轻Cd污染带来的危害,众多研究人员进行了镉污染土壤的植物修复研究,并提出工程修复措施、化学治理措施、农业生态修复措施和生物修复措施等技术,本文比较了各种修复方法的优势和局限,发现生物修复中的植物修复技术因其环保、经济等特点备受推崇.并重点阐述了Cd污染土壤植物修复的概念、类型和研究现状,进而对Cd污染土壤的植物修复技术进行了展望.
With the development of agriculture and industry, the heavy metal-cadmium pollution is becoming increasingly severe. In order to alleviate the effect of cadmium pollution, many researchers have engaged in phytoremediation re- search of soil polluted by cadmium and have proposed restoration measures, chemical treatment measures, agro-ecology restoration measures and phytoremediation technology etc. In this paper, comparing the merit and demerit of various ways of restoration, it is found that the phytoremediation technology is more preferred for it is more environment-friendly and economical. This paper focuses on the concept, types and research status of phytoremediation of cadmium polluted soil and the perspectives of phytoremediation of cadmium polluted soil is also discussed.
