• ( 3 ) the definition of soil series applied the method of direct nomenclature ( eg . qingjiang series ) , searches of soil series was the order : soil structure - the texture of hydragric epipedon - the proportion of clay and salt ( eg . apl - ap2 - g - clay loam - 0 . 54 ) , 10 typical soil sections were classified 10 soil series ( eg . qingjiang series beihe series ) and belonged to 5 subgroups and 4 groups of hydragric anthrosols
  ( 3 )土系采用直接命名法(如：清江系) ，其检索采取剖面构型+表层优势质地+粘砂比的性态检索顺序(如： ap1 - ap2 - c +粘壤土+ 0 . 35 ) ，被研究的10个典型土壤剖面被划分为清江系、北河系等10个土系，分别隶属于5个水耕人为土亚类、 4个水耕人为土土类。
• 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
  研究结果表明： 1太白山南坡土壤的主要理化性质随海拔高度的上升呈有规律的变化：随海拔高度上升，机械组成由粉粒砂粒粘粒逐渐过渡到砂粒粉粒粘粒，海拔1600m以下出现粘化层；土壤有机质丰富，表层有机碳含量一般在20g kg以上，有机碳含量随海拔高度升高而相应增加，海拔3500 3700m的灌丛草甸植被下有机碳含量最高；土壤呈酸性或微酸性，并随海拔上升， ph值略微降低，酸性增强，海拔2700m以上的土壤多呈盐基不饱和状态，表明土壤淋溶作用较强， ph值和盐基饱和度呈极显著正相关；土体与粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相对比较稳定，土体中sio _ 2含量较高， cao含量较少， sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和约占土壤矿质部分的92 ，矿质元素含量的顺序依次为： sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。
• 2 . the diagnostic surface horizons divided on the soils of the area are mollic epipedon , umbric epipedon and ochric epipedon . the diagnostic subsurface horizons are cambic horizon , argic horizon , histic evidence and mattic evidence . the diagnostic characteristics are sapric soil materials , folic soil materials , soil moisture regimes , soil temperature regimes , ferric property and base saturation
  本地区土壤划分出的诊断表层有暗沃表层、暗瘠表层和淡薄表层，诊断表下层有雏形层、粘化层，诊断现象有有机现象、草毡现象，诊断特性有6个：高腐有机土壤物质、落叶有机土壤物质、土壤水分状况、土壤温度状况、铁质特性、盐基饱和度。
