阐述了植物修复技术的含义，即利用植物去修复和消除有机毒物和无机毒物引起的土壤环境污染。介绍了对有机污染物修复的方法：①根收获，②叶表挥发，③植物降解；对无机污染物修复的方法：①收获生物量或将污染物进行生物挥发从而将污染物移出土体，②将污染物转变成为无生物活性的形态。收获生物量对于回收某些贵重金属是很有价值的。基因工程技术以及农业技术的综合运用可以更好地促进植物修复的效果。
The meaning of phytoremediation technology is expounded, that is, the use of plants to repair and eliminate soil environmental pollution caused by organic and inorganic toxicants. The methods of remediation of organic pollutants are introduced as follows: ① Harvesting of roots, ② volatilization of leaves, ③ Degradation of plants; Methods for remediation of inorganic contaminants: ① Harvesting of biomass or biological volatilization of pollutants to remove contaminants from the soil, ② the contaminant into a non-biological activity of the form. Harvesting biomass is valuable for recovering some precious metals. The combined application of genetic engineering and agricultural technology can better promote the effect of phytoremediation.
