Pioneer Plant Screening of Cd Pollution Soil--A Case Study of Hunan Shuikoushan Pb and Zn Ore District
Based on the analysis of soil samples from Pb and Zn ore district of Shuikoushan in Hunan,this article shows that the region is polluted by heavy metallic element Pb,As,Cd,especially Cd.This paper discussed the phyto-remediation management principle and its application in soil management,and found that Baoshan Violet ect.have certain enrichment ability that it can absorb heavy metal Cd.Respectively analyzed from the heavy metal enrichment ability,economic and social influence and ecological stability on the six species of plants,the composite index order is:Baoshan Violet>Chinese rose>Thlaspi calaminare> Solanum nigrum L.>small white hop>garlic.So Baoshan Violet was chosen to be the pioneer plant to cure study area heavy metal Cd pollution.
