Because of the distribution of macropore exhibit fractal rule, fractal theory can be used to study the structure of macropore. 由于土壤大孔隙的分布呈现分形规律，因此可以采用分形理论研究土壤大孔隙结构。
The structure of macropore plays an important role in water flow and solutes transport in soil, and influences the environment of underground water. 摘要土壤大孔隙结构对土壤中水流及溶质运移以及地下水环境有着深刻影响。
