Based on determination of heavy metal contents in soils and plants, understanding pollution of heavy metal in soils and plants, as well as the heavy metal accumulation in plants, in order to provide scientific basis for phytoremediation of heavy metals in mining areas. The determination and analysis on the concent of Zn, Cu, Pb, Cd, Mn was made in Niuba and southern mining area in Gejiu City. The result showed that the soil pollution from Cd is the most serious while the pollution from Zn was relative to minimum in Niuba abandoned mining area. In southern mining area, Pb in soil pollution was the most serious while Cu was relative to minimum Analysis on correlation between the heavy metal content in plants and soils was made based on the 5 plant samples (Pyracantha fortuneana, Zea mays, Acroptilon repens, Equisetum ramosissimum and Cucurbita moschata) collected from Niuba reclamation area and 5 plant samples (Corylus yunnanensis, Alnus nepalensis, Pyracantha fortuneana,Cupressus torulosa,Acacia dealbata) from recovery area of southern mining area. The results show that Pyracantha fortuneana has a better correlation with soil than other plants, Cucurbita moschata and soil have poor correlation, Corylus yunnanensis has better correlation with soil compared to other plants, Acacia dealbata has poor correlation with soil.

Arabis Alpina

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 plant Arabis alpina L. var. parviflora Franch, 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) of A. alpina were more than 1, and the TF of Pb was more than 1; the TF of Anaphalis margaritacea, Cyananthus inflatus and Arenaria orbiculata to Cu and Zn were more than 1, the TF of Juncus effusus to 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.
