  1. 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,學模型為: y = - 0 . 0212x ~ 2 + 1 . 8546x - 17 . 88 ,相關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,達到作物根集中層,否則水分很難被作物吸收,造成滴灌水的浪費。
  2. 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,統研究了流域土壤容重、土壤飽和含水量、田間持水量、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,同時為建立基於字高程模型( dtm )為基礎的流域水文模型積累基礎資料。
