Abstract: Abandoned lead-zinc mines are spread all over the country.Although the mining and utilization of lead-zinc minerals has brought a lot of material wealth,it has also affected the ecological environment.Inducing geological disasters such as subsidence.This article analyzes and investigates heavy metal pollution in abandoned lead-zinc mines in order to achieve the effect of treatment and rehabilitation of abandoned lead-zinc mines.Plants have the function of accumulating or accumulating heavy metals.Many studies have investigated plants growing in lead-zinc mines to find plants that repair heavy metal pollution in the mines.Based on comprehensive research,plants that have a good enrichment effect on heavy metals in lead-zinc mines include pteridophyta yarrow,pennisetum,miscanthus,annual wing,small flying awn,and full-leaf maran,dandelion,it is concluded that the small flying canopy,horsetail,and yarrow can effectively absorb heavy metals.Taking Qingyuan County's abandoned lead-zinc mine area as an example,heavy metal pollution evaluation is conducted and the coresponding treatment measures of the abandoned lead-zinc mine are proposed so as to provide some reliable for the evaluation and treatment of heavy metal pollution in abandoned mines.
