| 摘 要： | 通过研究元素含量在土壤表层和深层的比值，可以了解土壤表层元素含量的富集特征、成因和对环境的影响.将土壤中部分元素表层含量与深层含量进行了对比，统计、研究了比值系数及其分布特征，并对元素Cd区域性富集特征进行了探讨.指出成土母岩、元素化学特性、pH值、人类活动等对土壤中元素含量的富集具有重要的影响作用，应以地质、地球化学、人类活动等综合因素来研究土壤中元素含量的变化.

| Abstract: | The characteristics and reasons of element enrichment in upper soil layer and its impact on the environment can be understood by research on the ratios of element contents in upper and deep soil layers.This paper compares the contents of some elements in upper and deep soil layers to analyze the ratios and distribution characteristics,with an investigation of the regional enrichment of Cd.The result shows that the soil-forming rocks,element chemical properties,pH values and human activities play an important role in the enrichment of elements in soil.It is suggested that the study on the content changes of elements in the soil should be based on a combination of factors such as geology,geochemistry and human activities. |
