大面积低水平放射性污染土壤的植物修复研究现状

摘要

Radioactive contamination is a difficult environmental problem .As a new technology ,phytoremedi-ation of large area soil contaminated with low level radioactivity is attracting more and more attention .The con-cept and the basic principle of phytoremediation are introduced .The research progress with respect to contami-nation of 90 Sr ,137 Cs ,U and Pu ,obstacles of application and countermeasures ,are highlighted .Some sugges-tions on further studies are put forward .%对于大面积低水平放射性污染的土壤，植物修复是一种新型的治理技术。本文简单介绍了植物修复技术的概念，介绍了大面积137 Cs、90 Sr、天然U和Pu污染土壤的植物修复技术的研究现状及应用情况，提出了进一步的研究建议。
