- Abstract:
- In this paper,the contents of Pb,Cu and Zn in the plants and soil from a coal mine area in northern Xuzhou were examined,to study the enrichment ability of the dominant plants for different hea y metals.24 species (24 genera,12 families) of herbaceous plants in the region were found,including the 8 dominant plants.The results indicated that the average contents of Pb,Cu and Zn in the soil were 1.56,1.10 and 2.70 times to the background values of Xuzhou,and the content of Pb was positively correlated with Cu and Zn (P ＜0.01).The transfer coefficient of Erigeron annuus was more than 1.00,being 1.01 for Pb,being 1.42 for Cu and being 1.12 for Zn.The content of Zn in Artemisia lavandulaefolia was higher than the normal range,which reached 164.16 mg/kg.even,the plant’ s transfer coefficient and enrichment factor of Zn were 2.08 and 1.13.This two plants had the ability to enrichment the heavy metal,which can be used as a remediation for the ecological restoration of the local coal mine area.
