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。
Soil geochemical survey in Caoxian, Shandong Province is based on shallow soil samples 1/4 km ~ 2, deep soil samples 1/16 km ~ 2. The indexes of N, P, K, Cu, Zn, B, Mo, Mn, F, As, Hg, Pb, Cr and Cd were tested. Based on the statistics of the surface and deep soil geochemical parameters of these indexes, the differences between them and those of the world and the whole province were analyzed, and the correlations between the contents of soil elements in the surface and deep layers in the area were analyzed. The obvious characteristics of the surface soil element content are high F and low P, Zn and Mo. Most of the elements in the topsoil inherited the characteristics of soil parent material, but N, P, F and Hg were enriched in the surface soil by anthropogenic activities and sources of pollution.
