抗多元重金属植物的有效筛选及生态修复研究——以湖南柿竹园有色金属矿区为例
Study on Effective Screening and Ecological Remediation of Anti-multivariate-heavy-metal-plants—Taking Shizhuyuan Mining Area of Hunan Province as an Example
摘要
Abstract
[Objective]To screen the anti-multivariate-heavy-metal-plants adapted to the growth of mining area.[Method]The collected samples were dried and ground.Then the microwave digestion technique and Flame atomic absorption Spectrometry was used to determine the content of heavy metal ions Cu,Pb and Zn in the samples.Finally,the transfer coefficient and enrichment factor were calculated,and the plants with strong resistance and good effect were selected.[Result]The results showed that heavy metal contents were high in the Shizhuyuan mining area with low vegetation coverage.Pinellia ternata and Equisetum hyemale on Cu,Zn,Pb have better enrichment ability and strong transport capacity,and they were suitable for soil restoration.Radix puerariae and Ampelopsis sinica have good tolerance to Cu,Zn and Pb,and they suitable for enriching biodiversity and improving vegetation cover.[Conclusion]The study can provide reference for the treatment of heavy metal pollution in the mining area.关键词
