Abstract: Use the early remote sensing images, which have not been seriously damaged, after processed by some methods for the linear images, in combination of geological and topographic data, we made interpretation of the linear structures on the Shandong Peninsula. As an efficient tool for quantitative analysis of complex self-similar graphs, the fractal theory is used in the final interpretation of remote sensing results. The fractal dimension values of 21 cell zone are calculated with the box-counting method, and the fractal dimension isograms are derived. The research results show that the fractal dimension values of the faults on the Shandong Peninsula vary from 1.09 to 1.78 with the main structural direction in NE-trending and NNE-trending in the eastern and NW-trending and NNW-trending in the southwest of the study area; and the two groups of faults are complementary each other on the space.
