滁州地区土壤地球化学基准值与背景值研究

基于滁州地区多目标区域地球化学调查数据资料，统计获得了表、深层土壤地球化学基准值、背景值及相关的地球化学参数。研究表明：成土母质类型对土壤元素地球化学基准值影响显著，表层土壤元素含量相对于深层土壤既有继承性，又有差异性。在不同的土壤层的一些元素含量明显不同。土壤的形成过程和人类活动已经对土壤中元素含量的分布有显著的影响。因此，土壤地球化学基准值与背景值研究中应多考虑地质背景、物质来源等因素的影响，

A study on geochemical baseline value and environmental background value of soils in the Chuzhou area

Topsoil and deep soil geochemical baseline values, background values and relevant geochemical parameters were acquired from statistics of data of multi-target regional geochemical survey in the Chuzhou area. Study indicated that soil parent material has remarkable effect on geochemical baseline values of soil elements, and topsoil shows both inheritance and difference in element content compared with deep soil. In different soil horizons,some elements are ob- viously different in content. Soil-forming process and human activities have greatly affected element contents in their distribution in soil. More attention should be paid to such factors as geological background and material source in ana- lyzing geochemical baseline value and background value of soil.
