The results indicate that : 1. the main physical and chemical characteristics vary regularly : with rising of the altitude, there is a transition from silt > sand > clay to sand > silt > clay in the mechanical composition ; the argic horizon emerges below the altitude of 1600 meters ; the content of organic matter is enrichment, the content of organic carbon of epipedon is higher than 20 g / kg, while the content of organic carbon increases with increasing of altitude, and in the altitude of 3500 - 3700meters, the soils under the meadow have the maximum content organic carbon ; the soils appear acid - slightly acid reaction, the ph decreases appreciably and acid strengthen with increasing of altitude ; the soils higher than the altitude of 2500 meters are base unsaturated, indicating the soil leaching is strong, the ph and bs are distinct plus correlated ; the contents of sio2, al2o3, and fe2o3 of the soil body and clay are all relatively stabilization ; in the soil body, the content of sio2 is much high and cao is very little, the total contents of sio2, a12o3 and fe2o3 occupy 92 % of the mineral parts, the sequence of mineral elements is : sio2 > al2o3 > fe2o3 > k2o > mgo > cao > tio2 > mno
研究結果表明： 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化：隨海拔高度上升，機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒，海拔1600m以下出現粘化層；土壤有機質豐富，表層有機碳含量一般在20g kg以上，有機碳含量隨海拔高度升高而相應增加，海拔3500 3700m的灌叢草甸植被下有機碳含量最高；土壤呈酸性或微酸性，並隨海拔上升， ph值略微降低，酸性增強，海拔2700m以上的土壤多呈
鹽基不飽和狀態，表明土壤淋溶作用較強， ph值和
鹽基飽和度呈極顯著正相關；土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定，土體中sio _ 2含量較高， cao含量較少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ，礦質元素含量的順序依次為： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。
