Pole-axis system (PAS) is one of main modes of regional development in China. A fractal model of PAS, which considered poles and axes synthetically, was built to discriminate the phase PAS stating, and then a GIS computing model was developed for the fractal model of PAS. Urban-traffic system in Jinan, eastern China, which is the PAS's carrier in geo-space, was taken as an example. The results showed that: (1) PAS presented a fractal character when developing to a certain phase. The fractal model of PAS can effectively reflect its spatial structure state; (2) fractal, scale-free and space complexity were the different states of geo-space. We could deduce that spatial structure of PAS had experienced an iterative process of disorder, fractal, scale-free, spatial complexity and order with its development; and (3) the urban-traffic system in Jinan had shaped the rudimental structure of PAS, which was in the developing phase.
