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 。Some soils, such as sandy soils, have a loose crumb structure with good drainage, whereas in clay soils the particles are small and stick together to give a dense crumb structure and poor drainage
一些土壤例如砂土具有鬆散的結構，因而有良好的排水性，而在粘土中，由於土壤顆粒小而互相粘合導致粘土結構緊密排水性較差。Characterization of structure and performance for bonded soil with soil binders
土壤粘合劑粘結土壤結構性能表徵Soils : investigation and testing - line and or hydraulic binder treated materials - test for assessing the ability of a dry mineral treatment product to emit dust
土壤:調查和檢驗.線性和或液壓粘結處理材料.干礦物處理產品排放粉塵的能力評定試驗With increase of artificial forest age, the content of soil organic matter decreased sharply. and soil physical, chemical and biological properties of forest became worsen. from soil physical properties analysis, soil silt, clay, physical clay, aggregate degree and structure coefficient in topsoil increased with increase of artificial forest age and soil sand deceased
在土壤物理性質方面，隨著人工雲杉林齡的增加，土壤表層粉粒、粘粒、物理性粘粒、團聚度和結構系數降低，砂粒含量增高，土壤飽和持水量、毛管持水量及總孔隙和毛管孔隙在人工雲杉演替過程中表現出「 u 」型變化。Because these factors make change more often, soil time space variability is more bigger. the relationship of single factor between soil water infiltration capacities and certain influencing factor could be established quantitatively by means of soil water infiltration tests in indoor, there is negative correlation relation between soil water infiltration capacities and soil structure. there is negative correlation relation in high grit content and low physical clay content soil, and second - degree polynomial relation in high physical clay content junk structural soil between soil water infiltration capacities and soil moisture
由於這些因素在時刻發生變化，使得土壤的時空變異性較大，只能用室內土壤水分入滲試驗來定量確定土壤水分入滲能力與某些影響因素之間的單因子相關關系，土壤水分入滲能力與土壤結構之間呈負相關關系，土壤水分入滲能力與土壤含水量之間在土壤砂粒含量高，物理性粘粒含量低的無結構土壤中呈負相關關系，在物理性粘粒含量高的團粒結構土壤中呈二次多項式關系。Large amounts of lab experimellts showed that the consistency of swr sensor is very good, and the swr sensor have excellent results in every kinds of soil texture, especially in loam, clay and acid loam. there were not big variations among their measurement results
特別是壤土、粘土、酸性粘壤土等土質對測量結果的影響達到了極不顯著的水平，它們之間測量值的相關系數都達到了0 . 97以上。This research was conducted to : ( 1 ) understand the characteristic and pattern of trickle source infiltration, ( 2 ) study mulched crop evapotraspiration for cotton and corn in a arid climate sandy loam soils. according to the researches of the dissertation, the main results are as follows : ( 1 ) the shape of wetted soil volume is influenced by soil texture, discharge rate and the total volume of applied water in case of trickle source infiltration
本文以粘壤土為研究對象，對微源入滲特性規律進行了系統的室內試驗研究，並且對膜下滴灌大田作物棉花和玉米的需水規律進行了野外試驗，得到了以下幾點結論： （ 1 ）地表微源入滲土壤濕潤體的形狀受到土壤質地、供水強度和灌水時間的影響，一般為半個橢球體。The horizontal load actions of wind, wave, current and ice may cause the offshore platform sliding, and the platform sliding resistance includes soil cohesion, friction and soil resistance, so the bucket foundation platform should be designed to meet the requirements of stability against sliding to ensure the overall stability of platform
平臺在海上受風、浪、流、冰等水平載荷作用產生滑移，而土壤粘結力、摩擦力和土抗力是平臺的抗滑力，桶基平臺應滿足抗滑穩定的要求，以保證平臺的整體穩定性。The results are mainly as follows : sticky quality, tuber structure, the loose and tense degree, unit weight, ph value ( decreases in the few conditons that resulting acidity strengthening ), alkalinity increases in the same soil level, root quantity and macro - element content decreases ; there has a extraordinary difference between k, ca and mg, especially for pb and cd which shows that the collecting function of soil enhances under the disturbence conditon, and other micro - elements, such as zn > mn, cu, ni get decreasing. tourism activity is one of the key reasons for water body pollution. to different recreation types, the pollution degree has the obvious difference
