Distribution characteristics of elements in soil reflect the result of pedogenic process under the integrated impact of a number of natural and anthropogenic factors. In order to understand influences of human activities and natural processes on formation and evolution of Earth-cumuli-Orthic Anthrosols, two typical profiles of Earth-cumuli-Orthic Anthrosols were collected on the third terrace of the Weihe River in the central-west Loess Plateau for analysis of distribution characteristics of trace elements, including Cu, Zn, Pb, Rb, Sr. Results show that Cu, Zn, Pb, and Rb were relatively enriched in the buried paleo-surface horizon (2A) and paleo-argillic horizon (2Bt), where natural pedogenic eluviation and illuviation was playing a main role. Under the relatively warm and moist climate, Sr leaching was strong, showing entirely contrary distribution characteristics with obvious loss in the horizons of 2A and 2Bt. From the buried plow horizon(Aupb) to the subplow horizon(Aup₂) and the modern plow horizon(Aup₁), contents of Cu, Zn and Pb increased slowly. According to the calculated relative enrichment coefficient, only Zn in Aup₁ horizon of YL01 profile was obviously enriched with an enrichment coefficient higher than 1.1, showing that the influence of human activities on the contents of trace elements in Earth-cumuli-Orthic Anthrosols is generally quite weak.
