• 摘要：本工作为农业土壤、作物中有毒物质背景值协作研究的一部分。作者测定了北京地区129个采样点及32个剖面的农业土壤样品中的镍含量。在对分析数据进行数理统计的基础上,研究了不同土类土样中镍含量的分布类型,检验了剖面表层土(耕作层)同底层土的镍含量之间的差异。最后提出了北京地区农业土壤中镍的背景值。

• Abstract：This paper is a part of comprehensive study in determining background values of toxic elements in soils and crops in Beijing area. Nickel content in soil samples from 129 sites and 32 soil profiles has been measured. Based on statistical processing of the analytical data, distribution types of nickel content in various soils have been studied. In addition, differences between nickel contents in both top and bottom soil in soil profiles have been observed. Finally, background values of Ni in soils in Beijing area were presented.
