中文摘要：
利用土壤染色示踪剂，对初始水头分别为1．25，2．5和5．0cm三种情况下的实际入渗模式进行了全局性的观测。染色水流经过的区域被染色。通过照相记录染色分布获得实际流动模式。在此基础上，对水流运动的均匀性进行分析和评价。结果表明：即使在相对均匀的介质条件下，流动也表现出非均匀运动特性。入渗的均匀程度表现出随入渗水量的增加而增大的趋势，但过多的增加入渗水量。对于均匀程度的影响是有限的。
英文摘要：
In this study, dye tracer was used to visualize soil water flow patterns. The field experiments of dye infiltration included three initial water ponding depths： 1.25, 2.5 and 5.0 cm at the surface. Dye stained patterns was photographed and converted to binary images. Then the uniformity of soil water movement was evaluated. Results showed that heterogeneous flow patterns were observed in the relative homogeneous porous media. Although uniformity of the infiltration water distribution increased with ponding depths, uniformity of water distribution were only weakly increased with ponding infiltration depths.
