Abstract: The fractal structure feactures of the active faults in the upper reaches of the Qingjing River and the adjacent regions western Hubei are analyzed.It is shown that the magnitude of the fractal dimension of a single fault reflects the complexity of the structure of fault, the stage of its development and activity, while those of a small region reflects the differential movement of the faults of various regions reflects the differential movement of the faults of various regions.At the same time, the relation between the fractal dimension of an active fault and its activity is studied.Its value can be regarded as a quantitative measure.
