摘要：Aiming at the present serious situation of heavy metals contaminated soil in lead-zinc mining area of Huize County. This paper analyzed the the Pb, Zn, Cu and Cd enrichment characteristics of Imperata cylindrica growing in the different distance from the abandoned smelter. Results showed that the content of heavy metals in soils showed a tendency to decrease with increasing distance from the abandoned smelter, and the content of heavy metals in the soil 50m away from the abandoned smelter was the highest. There was a significant positive correlation between the contents of Pb, Zn, Cu and Cd in Imperata cylindrica and soil around the abandoned smelter. Four heavy metals of Imperata cylindrica showed that the content of the underground part was higher than that of the aboveground part. These Results showed that Imperata cylindrica could absorb and enrich a variety of heavy metals and had the characteristics of heavy metal resistance. Based on the characteristics of large biomass and fast growth rate, Imperata cylindrica has a good application prospect as a heavy metal pollution restoration plant.
