摘要
本文首先提出了重金属污染的概念,指出了土壤修复的几种基本方法及其优缺点,对我国土壤重金属污染的现状及土壤重金属污染植物修复技术的研究进展进行了概括和总结。阐述了桉树作为重金属污染富集植物的研究依据,认为将桉树用于重金属污染土壤的修复,一方面可在避免种植食用性植物前提下对重金属污染的土壤实行植物修复,另一方面可缓解当前木材资源供给压力,提高经济收益,具有明显的科学和现实意义。
Firstly,the concept of heavy metal pollution was put forward,advantages and disadvantages of several basic methods of soil remediation were pointed out.The status of heavy metal pollution of soil and soil heavy metal pollution in the progress of phytoremediation studies had been summarized and concluded.Eucalyptus was also described as a heavy metal pollution hyper accumulator that it would be used to repair heavy metal contaminated soils,on the one hand,to avoid planting edible plants in the context of the implementation of heavy metal phytoremediation of contaminated soils,on the other hand,also to alleviate the current pressure on supply of timber,and increase economic benefits with significant scientific and practical significance.
