摘  要:
介绍了大孔隙及大孔隙流的定义、多种表现形式及其重要特征、产生机理和室内外实验研究概况,以及染色示踪、切片、穿透曲线、张力入渗仪、X射线CT扫描摄像和雷达探测等方法的研究进展,揭示这些实验方法的优点与存在的问题.并指出由于影响大孔隙及大孔隙流的因素较复杂,应将大量的野外实验和室内实验相结合,同时改进观测方法,提高模拟手段,不断完善大孔隙流理论,使大孔隙流研究迈上一个新台阶.

摘  要:
In this paper, the definitions of soil macropore and macropore flow, their types, characteristics, generation mechanisms, and experimental methods in laboratory and field were introduced, and the research progress in their determination techniques, including dye tracing, slice up, penetration curve, tension infiltration apparatus, X-ray CT scanning, and radar exploration were summarized. It was indicated that because of the complexity of the factors affecting soil macropore and macropore flow, the experiments in laboratory should be combined with those in field, and the observation techniques and simulation measures should be further improved.
