土壤重金属污染的植物修复研究进展

Advances in Plant Remediation of Heavy Metal Pollution in Soil

植物修复技术应用于重金属污染土壤的修复,具有治理成本低廉,对环境扰动小,且没有二次污染等特点。研究植物修复技术主要是为了提高植物修复效率。包括对多种修复植物的修复效果及机理的研究,对不同种植条件下的修复效果的研究,以及利用基因工程的技术手段构造特定植物。

Phytoremediation technology is widely used in remediation of heavy metal polluted soils, which has the advantages of low cost, less disturbance to environment and no secondary pollution. The study of phytoremediation is mainly devoted to improving the efficiency. It includes the research on the effects and mechanisms of many kinds of restoration plants, the effects under different planting conditions, and build the particular plants by genetic engineering technique.
