对本区20个土壤剖面,79个土样进行光谱分析.结果表明,Co、Cu、Ni、Fe、Mn、Cr、Ti在土体中分布比较均匀,唯当有钙积层且物理性粘粒增多时,上述元素略增.含量顺序为:Fe>Ti>Mn>Zn>Cr>Ni>Cu>Co,与它们的克拉克值顺序基本一致.按土类划分,草甸盐土中的过渡元素最低,棕漠土次之,其它土类变化不大.诸土类中,钻的平均含量高于土壤克拉克值,Cr、Fe、Mn、Ni、Ti的平均含量则低于克拉克值.本区过渡元素的含量处于中、下水平.
The spectral analysis of 79 soil samples from 20 soil profiles in this area showed that the distribution of Co, Cu, Ni, Fe, Mn, Cr and Ti in the soil was relatively uniform, The contents of these elements are slightly increased in the order of Fe> Ti> Mn> Zn> Cr> Ni> Cu> Co, respectively, and their order of Clarke values are basically the same. , Followed by brown desert soil, but little change in other soil types. The average content of drillholes in all kinds of soils is higher than that of soil, and the average content of Cr, Fe, Mn, Ni and Ti is lower than Clarke. Elemental content in the middle and lower levels.
