Influence of Soil Forming Process on Element Content of Surface Soil in Yellow River Delta

In view of the abnormal areas of soil elements and organic pollutants found in the regional distribution, according to the previous sampling and testing results of surface soil, the abnormal areas in the investigation area of the Yellow River Delta were verified by the profile. Through sampling and testing, the vertical distribution of 12 elements, such As, Cr, etc., and the influence of soil forming process on 12 elements were analyzed, and the influencing factors of migration and transformation of heavy metal elements in topsoil were analyzed, which provided scientific basis for soil pollution and prevention.
