中国大陆壳体中深大断裂的分布具有分形结构特征。大陆全境的分维值为1．493，各构造区的分维值为0．827～1．624。活动区特别是地洼区中断裂构造分维值（1．236～1．624）显著大于稳定区即地台区的分维值（0．827～1．074），并且壳体结合部位的分维值大于壳内部位。断裂构造的分维值反映了区域大地构造演化、运动历史的复杂性和构造活动的强弱性，因而可作为大地构造研究的一个定量参数。 The distribution of deep faults in the crust of China has the fractal structure. The fractal dimension of the whole continent is 1.493, and the fractal dimension of each tectonic zone is 0.827-1.624. The fractal dimension (1.236-1.624) of the fault structure in the active area, especially in the depression area, is significantly larger than the fractal dimension (0.827-1.074) in the stable area, ie the mesa area, and the fractal dimension The fractal dimension is bigger than the inner shell. The fractal dimension of the fault structure reflects the tectonic evolution, the complexity of the history of the tectonic movement and the tectonic activity in the region, and thus can be used as a quantitative parameter in the study of tectonics.
