摘要：Contents of metal elements in soil covered lead-zinc tailing mine should be determined after long-term exposured with tailing ores, results should be compared with the requirements of metal contents in National Standards in order to measure the the application level of land. The investigation of this paper chose the representative soil samples of different altitude from multiple soil samples collected from the soil covered lead-zinc tailings mine mount in Cheng County, Longnan City, Gansu Province in China. XRF analysis was used to determine the kind and content of metal elements of the soil sample. The data were compared to make sure the changes of metal elements contents of soil samples with the altitude. The result found that the maximum content of Fe in each sample, and the content of Fe is quite different of the content of other metal elements in samples, while the samples had relatively low contents of Pb and Zn. Content of Cu in soil samples is lower than the Risk Screening Value of Soil Pollution in Construction Land, while contents of Pb and Cr were higher than that in Risk Screening Value of Soil Pollution in Construction Land.
