【摘要】 某些植物在生长过程中能从土壤中吸收特定的重金属(包括放射性核素),并在可被收割的部位富集,人们通过将植物富集部位的收割处理,达到处理污染土壤的目的,这就是植物修复法。利用植物修复法来治理土壤放射性污染问题具有绿色、廉价、清洁、环保的独特优点。本文着重介绍植物修复的机理、超积累植物的概念和研究进展以及影响植物富集效率的因素等。更多还原

【Abstract】 Some species of plant may absorb special heavy metals including radionuclide from soil.They concentrate in harvestable part of the body.By harvest,the nuclides are removed and the soil decontaminated is treated.This technology is called as phytoremediation,which has special advantages of being green,being cheap,being clean and environmental protection.In this paper,the mechanism of phytoremediation,the conception and research progress of hyperaccumulator and the factors affecting the accumulation function of plants were reviewed.更多还原
