Fractal theory was introduced in order to describe the ultrastructure of wood cell wall in this paper. The cellulose chain clusters around nano-scale were viewed as a fractal object that consists of many fibrillar structural units with different scales including microfibrils. On the basis of the morphological data of wood cell wall, fractal dimensions of multi-level fibrillar structural units were calculated by fractal-geometry approach, and then the morphological and structural characteristics of fibers as well as the influences on wood properties were investigated according to the dimensions. Besides, the fractal self-nesting character of the ultrastruture was also analyzed.
