摘　　要：土壤污染和退化问题日益突出,土壤改良剂的研究和应用在现代农业生产中越显重要。本文介绍了土壤改良剂的种类以及在植物固定技术和植物萃取技术方面的作用;总结了不同类型改良剂在放射性污染土壤改良中的应用和对植物修复效果的影响;并从吸附与离子交换、螯合与络合等方面阐述了土壤改良剂的主要修复机制。分析了常用改良剂在土壤放射性污染修复的研究现状和植物修复中的应用潜力,及其主要修复机制和存在问题,为将来开展深入研究提供有益的借鉴。With the increasing of soil pollution and degradation, it becomes more important to research and apply soil amendments in agriculture. This paper reviewed different kinds of soil amendments and their impacts on phytostabilization and phytoextraction techniques, and summarized the application of soil amendments in the radio- contaminated soils as well as their effects on the phytoremediation. The main repair mechanisms of the soil amendments are involved in adsorption, ion exchange, chelation, and complexation. The potential applications in the phytoremediation on radio-contaminated soils, as well as the main repair mechanisms and the existing problems were discussed.
