Characteristics of Macro-pore and Macro-pore Flow in Loess Soil

The concept of macro-pore flow and relevant research in the macro-pore flow was generally described, and the type and classification method of the macro-pore was analyzed. The function of the macro-pore in the soil water movement and the relevant theory were discussed. And the developing feature of the macro-pore and the type were analyzed in loess area. Moreover, the necessity of the research in the macro-pore flow in loess area is illustrated.
