The Application of Research Methods in Soil Macropores in Vadose Zone of Well Vegetated Slope

Abstract

Currently, there are various research methods for soil macropores in vadose zone of well vegetated slope. They include theoretical and experimental research methods, which are water breakthrough curve and tension infiltrometer, dying and slicing. The emerging and noninvasive technique of CT and NMR technology break through many bottlenecks for soil macropores study that have many advantages such as nondestructive, accuracy, comprehensiveness, quickness compared to traditional methods that have disadvantages of destructive, qualitative and the accurate results , but themselves possess significant shortcomings, for example, operation need professional technology and high expense that restrict the popularize and apply. Combining with many years of research experience of the author in macropore, based on theoretical and experimental methods, this paper introduces the commonly used methods in macropores study and their advantages and disadvantages. In the end, the existing problems were discussed and the future research was put forward.
