    摘要:

    本文在34个土壤剖面181个样品大量元素和36个剖面176个样品的Zn、Ni、Cn、Co、V等微量元素分析资料的基础上,讨论了天山及其邻近地区土壤成土的地球化学过程、这些元素的空间分异。认为天山及其邻近地区土壤的形成存在着三个主要的成土地球化学过程,即脱盐基过程、镁、钙积过程、钠积过程;随海拔高度的降低,水分减少、温度升高,元素的空间分异表现为:盐基自高山淋溶后,朝着盆地方向,按它们的盐类溶解度大小。分别富集钙、镁、钠等的盐类;微量元素含量自高山至盆地逐渐减少。

    Abstract:

    Based on analyzed results of major elements of 181 samples from 34 profiles and trace elements of 176 samples from 36 profiles, this paper discusses soil geochemical forming processes and the spatial differentiation of major elements and trace elements such as Zn, Cu, Ni, Co and V in soils of the Tianshan Mountains and their neighboring regions. During formation of the soils there are three main geochemical processes which are Ca and Na-leaching process, Mg and Ca-enrichment process and Na-enrich-went process. Spatial differentiation of the elements was from the leaching of Ca, Na and Mg in high mountain to the precipitating of salts of Ca, Mg and Na,respectively, according to the increasing of their solubility and gradual decrease of the total content of trace elements from high mountain to basins with lowering of altitude, decreasing of moisture, and increasing of temperature.
