摘要：
Based on analyzing the property of sediment size distribution of bed material in the river channel, the fractal characteristic of sediment particle has been defined, by means of fractal theory. Furthermore, the sediment particle fractal property has been applied to judge the process of armoring and stabilizing in the armoring experiment of bed material. The relationship between the riverbed roughness and its fractal dimension was obtained according to the experimental data. Finally, the relationship between bed material roughness and fractal dimension and representative diameter (d(50), d(90)) has been discussed respectively.
