摘要
准确识别土壤异常元素的成因和来源,识别其地质背景来源与人为污染的叠加量,可以为土壤污染评价与地球化学预警提供重要依据。利用山东省黄河沿岸土壤剖面的测量资料,根据土壤常量组分对微量元素含量具有决定性制约作用的特点,建立了利用土壤常量组分含量预测微量元素背景含量的数学方法,依据实测值和预测理论值可以定量地评价土壤人为叠加量,是评价土壤污染程度的途径之一。
It can provide important information for pollution evaluation and geochemical early-warning to identify the source of elements anomaly in soil. This paper gives a mathematic method to calculate the ＂geochemical background content＂ of trace elements in top-soil, which is based on the linear relation between major and trace elements in lower reaches of Yellow River of Shandong province. Then it can be used as a way to evaluate the soil pollution by quantitative analysis of man-made pollution in soil according to the difference between actual analysis and calculation data.
