| 摘 要： | 在日照市开展多目标区域地球化学调查，获取了表层土壤和深层土壤地球化学数据，通过对获得的地球化学参数进行统计分析，确定了日照市土壤地球化学基准值和背景值，认为日照市除部分元素或指标外，大部分元素或指标土壤地球化学基准值和背景值与全省土壤地球化学基准值和背景值接近。研究发现，日照市As，Cd，Cr，Cu，Hg，Ni，Pb，Zn等8种重金属元素背景值含量低于国家土壤环境质量标准的土壤一级标准限值，日照市土壤质量基本保持自然背景水平；而受工业化生产和城市化建设等后期人为活动影响，日照市表层土壤中Cd，C，Hg，N，P，S，Se，Corg等元素或指标出现明显富集，应引起重视。

| Abstract: | Based on the multiobjective regional geochemical survey in Rizhao city, geochemical data of the surface and deep soil have been obtained. Through statistical analysis of obtained geochemical parameters, geochemical reference value and background value of the soil in Rizhao city have been calculated. It is showed that geochemical reference value and background value of most elements or indicators in Rizhao city are similar to the geochemical reference value and background value of Shandong province. The background value of As, Cd, Cr, Cu, Hg, Ni, Pb, Zn and other heavy metal elements in Rizhao city are lower than the first class of the national soil environmental quality standards, which shows that the soil of Rizhao city are still in the position of a natural background. However, in the late stage of industrial production and urbanization construction, the elements or indicators of Cd, C, Hg, N, P, S, Se, Corg and so on in the surface soil of Rizhao city are significantly enriched, which should be paid more attention. |
