中文摘要：

综述了植物修复的相关机制及其进展和发展方向。随着一些功能基因的鉴定和分离，利用转基因技术提高植物对重金属的积累能力已取得了一些进展，开拓了植物修复的新领域。

英文摘要：

The mechanism, advance and developing direction of Phytoremediation technology for soil contaminated with heavy metal were summarized. Development has been achieved in increase accumulation of heavy metals in plants with transgenic technology because of the isolation and identification of functional genes. A new field has been exploited in phytoremediation.
