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 。

It can also restrain the decomposition of organic substances in the soil and the bind of nitrogen, and wash away the nutritious elements, such as magnesium, calcium, and potassium. the acid rain deprives the soil. it acidifies the rivers and lakes, and dissolves the heavy metal in the soil into water, therefore poisons the fish

它可以直接使大片森林死亡，農作物枯萎；也會抑制土壤中有機物的分解和氮的固定，淋洗與土壤粒子結合的鈣、鎂、鉀等營養元素，使土壤貧瘠化；還可使湖泊、河流酸化，並溶解土壤和水體底泥中的重金屬進入水中，毒害魚類；加速建築物和文物古跡的腐蝕和風化過程；可能危及人體健康。
