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。
Based on the analysis of trace elements such as Zn, Ni, Cn, Co and V in 181 samples of 34 soil profiles and 176 samples of 36 profiles, the geochemistry of soil-forming soil in Tianshan and its adjacent areas was discussed Process, the spatial differentiation of these elements. It is considered that there are three main processes of geochemical processes of soil formation in Tianshan and its adjacent areas, namely desalination, Mg, Ca accumulation and Na accumulation. With the decrease of altitude, the decrease of water content and temperature, The spatial differences are as follows: After the basalt leaching from the mountain, toward the basin direction, according to their salt solubility. Respectively, rich in calcium, magnesium, sodium and other salts; trace elements from the mountain to basin gradually reduced.
