摘要：In order to screen out the plants used to repair heavy metal pollution in the soil, five plants and surface soil were collected in the Huize lead-zinc mine area, centered on the hyperaccumulator plantArabis alpina L. var. parvifloraFranch, measured the heavy metal content of in shoot and root of plant and surface soil, and analyzed the characteristics of heavy metal accumulation in plants. The results showed that the soil Cd pollution in the Huize lead-zinc mining area was the most serious; among the five plants, the Cd bioconcentration factor(BCF) and translocation factor(TF) ofA. alpinawere more than 1, and the TF of Pb was more than 1; the TF ofAnaphalis margaritacea,Cyananthus inflatusandArenaria orbiculatato Cu and Zn were more than 1, the TF ofJuncus effususto Cd and Zn were more than 1. These five plants had good tolerance to heavy metals and were of great significance to the remediation and restoration of heavy metal contaminated soil in lead-zinc mining areas.
