山东黄河冲积平原区土壤地球化学特征

Geochemical Characteristics of Soil in Alluvial Plain of the Yellow River in Shandong Province

摘要:

山东黄河冲积平原区土壤地球化学调查是按每1km2采集1件表层土壤样品，4km2组合成1件分析样品，每4km2采集1件深层土壤样品，16km2组合成1件分析样品，测试Ag，As，Au，B，Ba，Be，Bi，Br，C，Cd，Ce，Cl，Co，Cr，Cu，F等54项指标。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，对其与全国同类参数的差异进行了分析，对比区内表层、深层土壤元素地球化学含量值的变化，认为大部分指标在表层土壤中的含量继承了土壤母质的成分特征，后期人类活动对其影响较小，但Corg，N，Se
