摘要
虽然土壤与食物链之间的依存关系使人们对土壤污染问题极为关注 ,但人类活动所排出的各类物质正使土壤污染呈现加重的趋势 ,有关污染土壤的修复研究正日益受到重视。生物修复技术是近 2 0年发展起来的一项用于污染土壤治理的新技术 ,处于实验室或模拟试验阶段的研究结果较多 ,商业性应用有待于该技术的进一步成熟和创新性技术的开发。本文重点就植物与微生物对重金属和有机污染土壤生物修复的机理及研究进展进行了讨论 。
Although the close relationship between soil and food chain makes people pay much attention to soil pollution, the fact is that soil quality is becoming degraded more and more seriously by the anthropogenic activities, and more studies about soil remediation are being conducted now. Bioremediation is an emerging technology to treat contaminated soils in the last 20 years. However, many research findings are situated on the experimental and simulating stage. Commercial application depends on its improvement and development of innovative technology. This paper reviewed the mechanism, effecting factors, and methods for enhancing bioremediation efficiency, and also discussed research aspects in this field.
