土壤重金属污染的植物修复

Phytoremediation of Heavy Metal Contaminated Soil

土壤重金属污染问题日益严重,植物修复技术以其投资少、不破坏场地结构、不引起二次污染等优点,成为重金属污染土壤修复与重建的研究热点。本文对土壤重金属来源形态、重金属植物修复模式、重金属超累积植物研究进展进行了分类、归纳与总结,为更好地利用植物修复土壤重金属污染提供一定的参考依据。

Soil heavy metal pollution problem is becoming serious increasingly. In recent years, phytoremediation technology is becoming a hot issue because of its Less investment, not to destroy the site structure, and to cause secondary pollution, the paper mainly focused on classification and summarization of soil heavy metal forms, heavy metal phytoremediation patterns, and the research progress on heavy metal hyperaccumulating plants. The aim of this work is supposed to provide a theoretic basis for further reasonable and effective utilization of phytoremediation on soil heavy metal pollution.
