山东曹县地区土壤地球化学特征

山东省曹县地区土壤地球化学调查是按浅层土壤样品1点/4 km~2,深层土壤样品1点/16 km~2。测试N,P,K,Cu,Zn,B,Mo,Mn,F,As,Hg,Pb,Cr,Cd等14种指标。在统计这些指标的表层、深层土壤地球化学特征参数的基础上,对其与世界、全省同类参数的差异进行了分析,并分析了区内表层、深层土壤元素含量的相关性,认为该区表层土壤元素含量的显著特征是高F而低P,Zn,Mo。大部分元素在表层土壤中的含量继承了土壤母质的成分特征,但N,P,F,Hg等受人为活动和污染源的作用在表层土壤中明显富集。

Geochemical Characteristics of Soil in Caoxian County of Shandong Province

On the basis of selecting one sample in the shallow layer within the scope of 4km2 and one sample in the deep layer within the scope of 16km2, geochemical survey has been carried out in Caoxian county. 14 kinds of indexs have been tested, such as N, P, K, Cu, Zn, B, Mo, Mn, F, As, Hg, Pb, Cr, Cd and other elements. On the basis of counting geochemical parameters of surface and deep soil, differences of the similar parameters in the entire province and in the world have been analyzed. The correlation between element content s in surface and deep soil has been analyzed. It is regarded that significant characteristics of element content in the soil are high in F and low in P, Zn and Mo. The contents of most elements in the surface soil inherited the compositional characteristics of soil parent material, but the N, P, F, Hg in the surface soil significantly enriched due to human activities and pollution sources.
