| 摘 要： | 重金属的排放造成了严重的环境问题。而消除重金属污染成为世界性的难题．有关研究结果表明。虽然重金属污染对植物有毒害作用，但是某些特殊植物具有从污染环境中吸收、转移以及积累重金属的潜能。从而修复土壤和水体等环境中的重金属污染．植物修复技术的出现虽然有很好的应用前景，但仍存在一些问题。

| Abstract: | Spread of heavy metals has given rise to severe environmental problems,and to eliminate heavy metal pollutants from the environment became a difficult task facing the world.Research results suggest heavy metal pollutants are toxic to many plants,but some special plants have the pot ential ability to absorb,transport within its body and accumulate heavy metals,and then remedy heavy metal pollutants in soil and water.Emergence of phytoremediation technology has provided a hopeful prospect,while the heavy metal phytoremediation technology still has some problems. |
