Abstract: 36 soil samples in tailings points and surrounding soil were collected to study the Xiaoqinling gold ore tailing slag.The heavy metal (Cr, Cu, Zn, Ni and As) pollution degree and its correlation was analyzed in different soil sampling points and profile.Also, a total of 12 typical plant samples such as reed, peanuts and artemisia capillaris were collected to measure the concentration of Cr, Cu, Zn, Ni and As.The plant bioaccumulation characteristics were assessed comprehensively by calculating heavy metal elements bioaccumulation coefficient and its transfer coefficient of plant samples.It was found that the main pollutants was Cu and Zn in the 0 to 10cm range of tailings slag and the Cu pollution was more serious, compared to the Zn pollution.For Cu and zinc content analysis in 0-30 cm soil profile, it was found that the average content of Cu and Zn showed a trend of 20-30 cm> 0-10 cm> 10-20 cm.Compared to the other plants, the amount of Cu and Zn in the ground part of the artemisia capillaris was higher.However, due to the morphological characteristics, the enrichment ability needs further verification.
