土壤大孔隙和土壤饱和导水率深度增加呈减小的趋势，并且变异性和复杂性很大。
The macropore and saturated hydraulic conductivity have increase with the increase of altitude and have great variability and complexity.
当土壤水吸力增大到一定值时，中间土层的土壤非饱和导水率反而大于底土层和表土层。
While the soil water suctions increased to some values, the unsaturated hydraulic conductivities in middle soil layers were higher than those in topsoil layers.
本文简述了标定的原理、田间土壤水分特征曲线和非饱和导水率的标定方法，还给出了水分运动参数标定的实例。
In this paper, the concept and the method of scaling are described, and some examples of scaling of soil water characteristic curve and unsaturated hydraulic conductivity are given.
