Results showed : ( 1 ) if the proportion of water in the soil is lower than wilting coefficient, and if irrigating water is very little, ( irrigating water is spreading horizontally and vertically ) the relationship between the horizontal width ( x ) and the ? rtical depth ( y ) is remarkable. the equation is y - 0. 02 12x2 + l. 8546x - 17. 88. the related coefficient is r = 0. 9350

    結果表明： （ 1 ）在土壤含水量低於萎蔫系數的乾燥條件下，進行微量穴滴灌，滴灌點土壤濕潤面直徑x與最大垂直面滲透深度y呈顯著相關，數學模型為： y = - 0 . 0212x ~ 2 + 1 . 8546x - 17 . 88 ，相關系數r = 0 . 9350 （ 2 ）在微量補水灌溉情況下，只有灌水量大於4000ml /穴，才能使滴灌水滲透到20cm以下土層，達到作物根系集中層，否則水分很難被作物吸收，造成滴灌水的浪費。
  3. Moreover, according to different land use types, bulk density shows the lowest value for the woodland while the highest value for the grassland and the subsoil of farmland, saturated soil moisture and field capacity exhibit the highest values for woodland while the lowest for the grassland and the subsoil of farmland, and the wilting moisture in woodland is also the highest and that in the farmland is the lowest

    不同土地利用類型土壤物理性質也存在顯著差異，容重以農地亞表層和草地較大，林地較小；飽和含水量和田間持水量以林地較大，農地亞表層和草地較小；萎蔫濕度則以林地較大，農地和果園地較小。
  4. The soil physical properties have obvious vertical distribution characteristic in the slope. the bulk density in sunlit slope is greater than it in sunless slope, and change in the follow order in the slope : top < middle < lower. while saturated soil moisture, field capacity, and wilting moisture are on the contrary

    在地形上，土壤物理性質具有明顯的垂直分佈規律，陰坡除土壤容重外，飽和含水量、田間持水量和萎蔫濕度均大於陽坡；同一坡度和坡向下，容重從坡下向坡上遞增，飽和含水量、田間持水量和萎蔫濕度均從坡下向坡上遞減。
  5. According to physiognomy, the bulk density changed as the following order : upland > hills > hillslopes > gully slopes, the saturated soil moisture arranged as : hillslopes > hills > gully slopes > upland, while field capacity and wilting moisture are as follows : gully slopes > hills > hillslopes > upland

    在地貌上，土壤容重呈現出塬面梁頂溝坡梁坡，飽和含水量呈現出塬面溝坡梁頂梁坡，田間持水量和萎蔫濕度均呈現出溝坡梁頂塬面梁坡的趨勢。
  6. The objectives of this study are : ( 1 ) collect the basis data about soil physical properties, soil moisture, infiltration and evapotranspiration in the catchment scale for developing a catchment hydrological model, based on the dtm, ( 2 ) provide the hydrological information in the catchment scale for developing agricultural production, vegetation rehabilitation, and reasonable land using in this region. the main conclusions drawn from this study are : ( 1 ) the soil physical properties, including bulk density, saturated soil moisture, field capacity, and wilting moisture, were measured at 56 plots across the catchment

    為此，本文以黃土高原溝壑區典型小流域?王東溝為研究對象，通過大量的野外測定和室內分析，系統研究了流域土壤容重、土壤飽和含水量、田間持水量、萎蔫濕度、土壤入滲性能、土壤含水量和蒸散量的空間變異性，以期為該區農業生產、植被恢復和土地合理利用等提供科學的依據，同時為建立基於數字高程模型（ dtm ）為基礎的流域水文模型積累基礎資料。
  7. It was found that the soil physical properties had significant spatial variability in the catchment scale because of the joint - influences of land use, topography, physiognomy, and other factors. the spatial variation is small for field capacity, moderate for wilting moisture and bulk density, and great for saturated soil moisture

    受地形地貌和土地利用等因素的綜合影響，土壤物理性質在流域尺度內存在顯著的空間變異，飽和含水量的空間變異性最大，土壤萎蔫濕度和土壤容重居中，田間持水量空間變異最小。
  8. Saturation and capacity change with depth similarly. the nuggets of bulk density and wilting point are very tow, and the nugget of soil water content is decreased with depth

    容重和萎蔫含水量的塊金值都很小，尤其是萎蔫含水量在各層的塊金值都相等，含水量的塊金值隨剖面深度而降低
  9. Thirdly, this paper compared the different responses of plants to these two stresses, the change of the defensive enzyme activity and the rate of losing water of leaves was different at two different stresses. the rate of losing water of leaves at drought stress was more rapid than that at salt stress, the leaves would wither and the change of activity of enzymes notably at drought stress, these results showed that the damage to plants was result from the oxidation at drought stress. at salt stress, the content of relative water of leaves changed slightly as well as did the activity of enzymes, these results showed that the damage to plants was caused by poison of ion and lack of nutrition

    三、通過研究兩種冰草植物對兩種脅迫的反應指出乾旱脅迫和鹽脅迫通過不同的途徑對植物進行傷害，主要表現在葉片的失水速率和保護酶活性的變化，乾旱脅迫短時間內葉片失水速率很快，葉片萎蔫，引起保護酶活性顯著變化，表明乾旱脅迫主要是通過氧化脅迫對植株造成傷害，而鹽脅迫下葉片相對含水量幾乎保持不變，表明鹽脅迫對植物的傷害主要通過離子毒害和營養虧缺造成。
