  1. 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 。
  2. The concentrations of copper, lead and zinc in the shoot of e. splendens were affected by chemical and physical properties, such as full contents of heavy metals in soils, soil ph and organic carbon content, etc. the shoot can accumulate copper more on the red sandy paddy soil collected from dongxiang country, jiangxi province, than on silt paddy soil from fuyang country, zhejiang province. e. splendens took up much less copper from fuyang soils, the concentrations of zinc and lead in shoot were not also quite low

    在酸性紅砂土上植物對銅的吸收和富集隨土壤銅含量的增加而顯著升高；而在銅、鋅、鉛復合污染的中性泥沙土上海州香薷體內銅含量和積累量不高，處于正常植物生長范圍內，植物體內鋅、鉛含量及其積累量也不高，海州香薷對重金屬的吸收和富集能力有限。
  3. In the first step, quantitative and qualitative characteristic of soils influenced by soil microalgal were studied in this step. in this study, four different algal ( chroococcus, chlorococcum, navicula and chalmydomonas ) and one algal mixture, which were formed by the above four algal species, were cultivated in two different mediums ( soil and double distilled water ), under regular illumination or dark condition respectively. we estimated the environmental ph, the microorganism biomass ( not including algal ), and the organic matter content very 20 culture days and estimated the available phosphorus after 60 culture days. we got the results by making graphs and extreme - difference analysis after 0, 20

    實驗以土壤（經過高溫燒制除去微生物和土壤有機質的影響）和水（重蒸水）為兩種不同的基質，在基質中接種五種相同重量的土壤微藻藻液（立方色球藻、土生綠球藻、舟形藻、沙角衣藻以及由四種藻種形成的混合藻液） ，分別進行見光和和黑暗培養，在0天、 20天、 40天和60天時，測定環境ph值、微生物量（不包括藻類） 、有機質含量，進行極差分析和圖形比較。
  4. There was notable relation between content of organo - mineral complexing and degree of organo - mineral complexing, which implicated the high degree of complexion of organic matter in soils, most of the organic matter composed organo - mineral complexes by combing the mineral colloids

    土壤復合量與復合度達到顯著相關，反映出土壤中的有機物質復合程度很高，大部分有機物質與無機膠體形成有機無機復合體。
  5. Soils : investigation and testing. determination of the organic matter content. soil chemical test

    土壤:調查和試驗.有機物含量測定.土壤化學試驗
  6. Influence of organic matter content on infiltration capacity of field soils

    土壤有機質含量對土壤入滲能力影響的試驗研究
  7. Influence of organic matter content on infiltration capacity and parameter in field soils

  8. The soils in the region were characterized by thin layer, weak structure, gravel / fragmental composition, compacted surface and drought, etc. soil water properties are important factors affecting vegetative rehabilitation in spite of low soil organic content and lack in soil nutrients

    乾熱河谷的土壤特徵表現為土層淺薄、土壤結構差、土壤石質粗骨性強或表土緊實、土壤乾旱等。雖然土壤有機質含量低、有效養分也較缺乏，但是土壤水分性質是植被生長恢復的關鍵制約因素。
