摘　　要：得耳布尔铅锌矿位于森林沼泽景观。通过对低温富有机质环境中土壤元素的表生地球化学特征的研究表明,土壤中元素地球化学行为受到到基岩、土壤粒级、铁锰氧化物、有机质、酸性地表水的控制;残积层和腐殖层元素存在形式主要是铁锰氧化物态,铁锰氧化物对元素次生富集起到了很大的作用;有机质对元素的吸附作用受到土壤粒级、层位和有机质含量的影响。The Deerbuer Pb-Zn deposit is located in a forest and swamp area. Element geochemistry of soil in the low temperature and rich organic matter environment was studied. It is shown that element geochemistry is influenced by rock, soil granularity, iron-manganese oxides, organic matter and acid precipitation, and that modes of occurrence of elements in eluvial and humus layers are mainly iron-manganese oxides which play a significant role in element enrichment. The adsorption of organic matter is affected by soil granularity, horizon, and organic matter content.
