Abstract: The types of plant community and the floristic compositions in the leadzine abnormal and normal areas identified by geochemical exploration are basieally similar. According to the chemical analysis the contents of Pb, Zn, Cu, Cd of plants and soils in abnormal areas are higher than in normal areas. The absorption coeffieients of heavy metal elements by plants change with various chemical element, in the order of Cd>Zn, Cu>Pb. The results of the correlation analysis showed that the linear relationship between the contents of Pb, Zn in plant communities and in soil are singnifieant. There is a considerable linear correlation of Pb, Zn, Cu, Cd in soil and in Carex callitrichos, Sangnisorba officinalis, Polyoinum lopothitolium, Spirea pubescens, respectively. A close correlation presented in the contents of Pb, Zn, Cu, Cd between Carex callitrichos and soils. The multiple correlation coefficient is 0.999 (N=8, P<0.01). It may be suggested that Carex callitrichos can indicat the contents of Pb, Zn in soils.

Key words: Lead-zine mining area, Phytoeommunity, Correlation analysis Element content.
