摘　　要：从土壤结构特征的描述、土壤水力特性的研究等方面 ,综合评述了 80年代以来国内外应用分形理论描述土壤水力特性参数及分形特征的研究进展 ,并探讨了其发展方向和前景。In this paper, describing soil structure and characterizing soil hydraulic properties with fractal theory are reviewed since 1980s Based on the theory, the fractals of porous media are characterized by fractal dimensions of soil pores, particle size distribution and particle surface or volume of soils, and the fractal models of soil water retention characteristics and hydraulic conductivity are determined accordingly Also the advances of fractal theory in hydraulic properties are discussed
