摘      要：Natural contents and distribution of trace elements in soils of the Dam River and Tuotuo River basins are demonstrated in this paper. By using contrasting methods. it is found that the content of trace elements of soil in the region is at the lower limit of the world s soil content level, that the tendency of the average trace element content in the four main types of soil is shown as: alpine mountain meadow soilmarsh soilalpine mountain steppe soil alpine mountain cryogenic soil. the average content of trace elements such as Cr. Co, Zn, Cu, Hg, Pb, Mo, Mn and Ni in the Dam River basin is higher than that of the Tuotuo River basin except that of the elements Ba and Sr. In addition. through correlation analysis. the relationship of intergrowth and association among soil elements are revealed.
