太白山山地土壤中的微量元素

用化学方法测定了陕西省太白山山地土壤中氟铜。锌、砷、钼、锑、钨、汞、铅和铋等元素的含量。结果如下:土壤中微量元素含量主要取决于成土母质；微量元素在剖面中的分布受成土过程影响；铜、锌、钼和汞的平均含量均低于世界土壤。

THE TRACE ELEMENTS IN SOIL OF THE TAIBAI MOUNTAINS

The content was measured of F,Cu,Zn,As,Mo,Sb,W,Hg,Pb and Bi in soil of the Taibai mountains in Shaanxi Province by chemical methods,Results obtained might be summarized as follows: The contents of trace elements in soil were largely dependent on their parent materials;The distribution of the trace elements in the profile was affected by soil forming proeess;The mean content of Cu, Zn,Mo and Hg in the soil is lower than that in the world.
