  1. Meanwhile, most aspects about this perspective are concerned, which include quantification of the soil water background of the plateau area, the regional spatial variation of soil water background and variation along the slope, mosaic structure and seasonal changes etc. the results show that : ( 1 ) for the fundamental circumstance for vegetation development is the original debilitated slope, so the perspective of soil water background specially for the loess plateau refers to the soil water conditions on the original slope. ( 2 ) the value of soil water background appears to be a descending trend from south to north based on the difference of vegetation zones. in the forest zone, soil moisture contents beneath 3m depth from the soil surface are more than 12 % usually ; in the forest - pasture zone, the values of soil moisture content beneath 4m depth underground are more than 6 % and stable, and tend to be ascending while the depth increases ; but the values in the dry pasture zone is lingering between 4 % to 6 % from the surface layer to sub - layers

    發展了「土壤水分背景」的概念，並以之為基礎對其各個方面進行了研究，使之形成一個相對獨立和完整的體系，主要包括黃土高原土壤水分的背景值、土壤水分背景的區域分異、坡面分異、鑲嵌結構及其季節分異等： （ 1 ）由於植被生長發展、演替的基礎階段是天然草被群落，故認為黃土高原的土壤水分背景在概念上是特指該區天然草被群落下的土壤水分狀況； （ 2 ）黃土高原的土壤水分背景值，根據植被地帶的不同表現出自南向北逐漸降低的規律：森林地帶3米以下土層水分背景值普遍穩定地高於12 ，森林草原地帶4米以下土層水分背景值穩定大於6 ，且均隨土層的加深水分含量逐漸增加，而草原帶的土壤水分背景值自土表至底土層一直在4 6之間徘徊。
  2. Under the filtration irrigation, the water content could remained a fit range from 14 to 22 percent in the layer of 20 to 70 cm deep, however, the general irrigation could reduce the moisture utilization during the growing period of the maize. ( 4 ) filtration irrigation could well adjust the soil temperature so that the root system made a sufficient absorption of the moisture and mineral nutrinents

    從土壤含水量測定分析看，在20 70cm土層，滲灌水分含量一直維持在玉米正常所需的14 22范圍內，而漫灌分兩次灌水，在每次灌水前一段時間水分含量要下降到14以下，出現水分脅迫，尤其影響到玉米的前期生長。
  3. Considering the actual testing, the influences of such factors as the thickness of the steel plate, the moisture content of the concrete and oil paint layer on the test are taken into account in experiment

    考慮到實際測試的情況，本文考慮了鋼板厚度，混凝土含水量，油漆層等因素對測試的影響並分別進行了試驗。
  4. 4. soil n2o discharge flux responsible for the different treatments were affected by the different soil factors in the winter wheat growing stages. under no planting conditions, the moisture regime in the 0 to 5cm soil layer mostly made the soil n2o discharge flux adding in the mulch treatment, and the content of nitrate nitrogen in 5 to 10cm soil layer in the no mulch treatment

    4在冬小麥生育期內，影響不同處理土壤中n _ 2o排放通量的主要土壤因子為：無種植情況下，覆膜所導致的膜下（ 0 - 5cm ）土壤水分積累是引起土壤中n _ 2o排放通量增加的關鍵；無膜時較淺層土壤（ 5 - 10cm ）中no _ 3 ~ - - n濃度對土壤中n _ 2o的排放至關重要。
  5. After a rainfall end, soil moisture content of cultivated layer is nearly stable within a certain period that is one week if rainfall leads to saturated runoff generation and is the optimal duration of fertilization

    若有降雨使土壤飽和（產流）發生， zwt天後，在無外界水源條件下，土壤含水量大約有一周的穩定期，這一時期是施肥的有益時期。
  6. Thin - layer drying experiment of alfalfa was done on thin - layer drying experiment table to study different lengths of alfalfa ' s moisture content and drying rate changing with the time under the two circumstances of crushed stem and the uncrushed stem

    摘要在薄層乾燥試驗臺上進行薄層乾燥試驗，研究不同長度苜蓿段在壓扁和未壓扁兩種情況下含水率及乾燥速度隨時間的變化規律。
  7. The results show that the cohesion of unsaturated soil changes greatly, and the friction angle changes a little with soil moisture content it is also shown that the deeper of soil layer, the smaller of the extent of shearing strength improved

    結果表明，植被具有提高非飽和土抗剪強度的作用，黏聚力增加較大，內摩擦角增加相對較小；土層越深，土壤抗剪強度提高的程度越小。
  8. It has shown an evident phenomenon, called " island of fertility " in the shrubs because there were high content of medium - fine soil particles ( 0. 25 ~ 0. 02mm ) and relatively abundant soil moisture, organic matter, total n, available k and hydrolytic n on the soil surface under the shrubs, and furthermore, the content of soil moisture and nutrients gradually decreased from the center of the shrubs to its edge in this soil layer

    灌叢地表層（ 0 5cm ）土壤的中細粒子（ 0 . 25 0 . 02mm ）含量高，並且土壤水分、有機質、全氮、速效鉀和堿解氮含量相對優越， 「沃島」現象明顯，而且，由灌叢內向外，含量逐漸降低。灌叢地下層（ 20cm以下）土壤含水量從灌叢中心向邊緣逐漸增加。
