    結果表明： （ 1 ）在研究區域不同類型的下墊面條件下，夏季土壤水分在濕潤研究區呈明顯的單峰偏態分佈，且以分佈擬合效果為最好；而在臨近綠洲的沙漠研究區則呈多峰分佈，冬季呈分佈。
  2. 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。
  3. After the observation and analysis on the uniformity coefficient of irrigation and the distribution of soil moisture under each different treatment, a result was got that 35cnrs embedded depth is comparatively appropriate for vegetable cultivation for the high uniformity coefficient and the vegetable cultivation for the high uniformity coefficient and the concentrated distribution of irrigation water in the main root zone

    通過對各處理灌水均勻度和土壤水分分佈的觀測、分析，認為滲灌管埋深35cm時對蔬菜栽培是比較合適的。此時灌水均勻度高，灌溉水大部分分佈在蔬菜主要根系區。
  4. Study shows that great rainfall influences soil slope safety factor markedly, magnitude of rainfall intensity has a great influence on slope safety factor for steep slope under certain coefficient of saturated conductivity, the surface plant roots affect unsaturated zone seepage field distribution and postpone unsaturated zone moisture content ' s increase, so the soil slope safety factor is enhanced finally

    分析結果表明，在土體飽和滲透系數一定的條件下，強降雨對土坡穩定系數影響顯著；土坡越陡，降雨強度大小對土坡安全性影響就俞顯突出；土坡表層植物根系的存在影響非飽和區滲流場分佈，可以延緩非飽和區含水量的增大，土坡穩定系數得到提高。
  5. The model is a physical model based on hydrodynamics. it also takes account of the smooth slopes, which are typical topographies in plain areas. with these two considerations, soil moisture in vadose zone has been focused on

    該模型是基於水動力學的物理模型，並充分考慮到平原區地勢比較平緩這一特點，因此將包氣帶土壤水視為重要的研究對象。
  6. On the basis of all these, the paper researches that the soil moisture content reduces slowly after 7 days ， so establishes a main criterion of evaluating watering feature - the increment of average soil water content in 7 15 days. according to these theories, we draw an conclusion - water is injected at the position away from seed zone 3. 5 ( cm ), 6 ( cm ) deep with vertical flat nozzle, the effect of watering is better at the operation speed of 0. 9m / s

    得出7天後土壤含水量呈緩慢變化的趨勢，進而提出了以7 15天平均土壤含水量與初始含水量的差值作為評價坐水性能的指標，以此為依據得出在機組作業速度由0 . 5m / s增加到0 . 9m / s的情況下，採用豎扁（不帶翅）施水管將所需的水施到種子帶橫斷面內3 . 5cm ，深6cm的位置，坐水效果較為理想。
  7. The plants growing on the land surface can be affected by the occurrence and movement of water and salt in the aeration zone. in order to understand the characteristics of occurrence of water and salt in the aeration zone, we installed three tensionmeter systems. which includes 35 ceramic cups, in the soil of ejnqi oasis on the downstream of heihe river in inner mongolia province. the moisture potential distribution in aeration zone was observed, and the samples of water and soil were collected along the heihe river

    為了了解綠洲包氣帶水分、鹽份的分佈特徵，我們在黑河下游的內蒙古額濟納旗綠洲安裝了3組35支負壓計，觀測包氣帶中的水土勢，並沿黑河河谷從下游的額濟納旗到中游的張掖採集土樣和水樣，測試土壤的易溶鹽和潛水的化學成分，從包氣帶中水土勢和鹽份兩個方面來研究乾旱地區水分和鹽份在包氣帶中賦存和運移規律。
  8. Based on five years regional water - salt monitoring data and related hydrological and weather information in the smaller scale experiment zone ( shahaoqu ), the regional water - soil ( salt ) environment regime including grounder water table depth, water quality, superficial layer ( 0 - 40cm ) and middle layer ( 40 - 70cm ) soil moisture and saline concentration are simulated, tested and predicted using bp model. at the same time, the rbf model is be used to calibrate the results of bp

    以一個小尺度試驗區的多年區域水鹽監測資料及水文氣象資料為建模依據，對試區非凍期（作物生長期）的地下水位、地下水質、土壤水鹽（ o - 40cm ， 40 - 70cm ）的水-土（鹽）環境狀況進行了較為深入全面的模擬預測，並進行了rbf模型預測結果的對比。
