中文摘要：

汞是一种全球性污染物。随着工业的发展、汞矿开采的加速,土壤汞污染日益严峻,给生态环境和人类生活带来了严重的威胁。因此,汞污染土壤的修复问题受到了广大学者的关注。针对受污染的土壤修复问题,植物修复技术具有成本低和不会给环境带来新的危害等特点。本文对目前国内外汞污染土壤修复植物修复技术的研究进行了综述,介绍了转基因技术在汞污染土壤中的应用,探讨了转基因技术在环境治理和环境修复中潜在的应用价值。

英文摘要：

Mercury（Hg） is considered as a global extreme destructive pollutant.Now,the problem of contaminated soil was more and more serious because of industry development and mercury mine exploitation,which took painful results not only to environment,but also to mankind.So,this problem has been concerned by many scientists.Phytoremediation of mercury-contaminated soil had many advantages,including low cost and environment-friendly.This paper introduced the technology of phytoremediation in mercury contaminated sites,especially,the application of transgenic technology in mercury contaminated soil.The significance of transgenic technology in mercury contaminated soil was also discussed.
