摘要
城市工业废弃地可能已经受到原有生产活动产生的有毒有害物质的污染影响,原有生态系统遭到严重破坏。尤其是废弃矿山,土壤重金属重度污染,生态恢复极为困难。植物群落的修复成为矿区生态系统修复中最为关键性的一步。通过对植物进行野外调查,并测定矿区的优势植物对重金属的富集与转移能力,筛选出适合矿区土壤状况的重金属忍耐型植物,然后优选植被配置模式,并加强后期维护管理,完成植物修复工程。
The original site of removal enterprise, which is urban derelict land, may be contaminated by residual toxic and hazardous material from the original production activity. The original ecosystem was rather seriously damaged. The compound pollutiont of the heavy metal is in the nonferrous metals mine land. It is very difficult for this kind of pollution to be restored. However, the phytoremediation technology is the most effective measure for the soil heavy metal pollution control in metal mine areas and the improvement of eco-environmental quality. Thus, the field investigation towards plants and the meast^ing on the enrichment and metastasis potential towards heavy metal caused by dominant plants are carried out in order to screen out the heavy metal resistant plants suitable for the soil condition in this research area. Then the perfect pattern of forest vegetation is selected and the late maintenance management is strengthened to complete phyto-remediation project.
