| 摘 要： | 平阴县土壤地球化学调查是按每1km^2采集1件表层样，4km^2组合成1件分析样，每4km2采集1件深层样，16km^2组合成1件分析样，分析测试Ag，As，Au，B，Ba，Be，Bi，Br，C，Cd，Ce，C1，Co，Cr，Cu，F等54元素或指标；统计了这些元素或指标的土壤地球化学基准值与背景值等参数；研究了区内土壤地球化学基准值、背景值与全国、黄河下游流域土壤及平原区、丘陵区土壤的差异；对比区内土壤地球化学基准值与背景值变化，认为区内大部分元素或指标在表层土壤中的含量继承了土壤母质，后期人类活动对其影响较小，但C，Cd，C1，Hg，P，N，S，Se，Corg等元素或指标在表层土壤中已明显富集，表明表生作用和人类活动等因素已对这些元素或指标的含量变化与分布分配产生明显影响。

| Abstract: | On the basis of collecting one surficial sample in each 1 km^2 and combining them into one sample in each 4km^2, collecting one deep sample in each 4km^2 and combining them into one analyzing sample in each 16km^2, geochemical survey of soil in Pingyin county is carried out. In this survey, 54 elements and ratios are determined, such as Ag, As, Au, B, Ba, Be, Bi, Br, C, Cd, Ce, C1, Co, Cr, Cu and F; geochemical referencevalue and background value of soil are statisticed, and difference between this area and other regions in our country and the Yellow river region are contrasted. It is regarded that many elements and ratios in surficial soil contained matrix soil, and can be hardly effected by human movement. C, Cd, C1, Hg, P, N, S, Se and Corg are concentrated evidently, which reflects that epigenization and human movement will effect variation and distribution of elements contents obviously. |
