| 摘 要： | 报道了中国黄土中40个元素的背景值,并以F、Cr、Mn、Co、Ni、V、Cu、Zn、As、Se、Cd、Pb、Hg等13个元素为例,讨论了其在黄土高原的分布与含量。利用趋势面分析等数理统计方法,揭示了黄土中元素的某些环境地球化学特征及元素背景值的分异规律。结果表明,黄土的元素背景值具有三维的分异特征,黄土的质地及沉积的生物气候环境黄土是影响背景值分异的主要因素。为中国黄土的风成学说提供了佐证。

| Abstract: | The background content values of 40 elements and the distribution patterns of F, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Cd, Pb, and Hg in loess of China were studied. By using trend surface analysis and other statistical methods, it was demonstrated that the grain sizes of loess and the bio-climatic environment of loess deposition are main factors influencing the variation in elemental abundances, providing further evidence for the eo-lian theory of loess formation in China. |
