本文介绍本院野外试验场包气带土壤结构和渗透性参数实验分析的主要方法及其结果。实验结果表明 ,所研究剖面的土壤不均匀程度较高 ,平均不均匀系数为 14.7;饱水渗透系数在垂直与水平两主轴方向离心率在 0 .6 5～ 1.0 0之间 ,剖面各层平均离心率为 0 .93,故从地下水动力学角度看 ,该包气带土壤可认为是各向同性介质 ;而不同土壤层渗透系数之间有明显差异 ,故整个包气带为非均质。饱水渗透系数在剖面的上、下段大 ,中段小 This paper introduces the main methods and results of experimental analysis of soil structure and permeability parameters of aeration zone in our field. The experimental results show that the profile of the study area has a high degree of soil heterogeneity with an average non-uniform coefficient of 14.7. The eccentricity of the saturated water permeability coefficient in the vertical and horizontal principal axes is between 0.56 and 1.05, The eccentricity is 0.93. Therefore, from the point of view of groundwater dynamics, the soil in the zonal aeolian zone can be regarded as isotropic medium. However, the permeability coefficients of different soil layers are obviously different, so the whole zonal zone is heterogeneous. Water permeability coefficient in the profile of the upper and lower large, middle small
