| Abstract: | Macropore flow is a natural and ubiquitous phenomenon in soil environment. Research on macropore flow involves studying mechanisms of soil water movement from homogeneous to heterogeneous fields, so it has become research focus in soil physical science. Understanding of mechanisms on macropore flow would provide useful information for irrigation, fertilization, crops planting and pollution tendency simulating. This paper introduces present research situation of macropore flow from classification standards, the influencing factors and quantitative methods, the deficiency of present research and research directions are discussed. The purpose of this paper is to provide some new ideas for deeply studying macropore flow. |
