以分形理论为基础，采用网格覆盖法，对广东省主要活动断裂进行分形研究。研究结果表明，广东省内主要活动断裂在分形标度区间12.5～100 km具有较好的统计自相似性，断裂分布的分形维数有效地描述了断裂的空间展布特征，全部断裂分形维数为1.5823，北东向断裂为1.4342，北西向断裂为1.1157和近东西向断裂1.0394，并且北东向断裂与北西向断裂的分布呈现一定的互补性。结合断裂分形维数等值线与历史地震活动，初步探讨了断裂分形维数与地震活动的耦合关系。

Based on the fractal theory,the fractal geometry is applied to studying the active faults system in Guangdong Province.Results indicate that the spatial distribution of all faults in Guangdong Province is a distinct fractal set with self-similarity in the non-scale range of 12.5 -100 km,and the fractal dimen-sion,obtained by the box-counting method,interprets well the characteristics of the spatial distribution of faults.The fractal dimension of all faults in the study area is 1.582 3,that of the NE faults 1.434 2 and that of the NW faults 1.1 15 7 and EW faults 1.039 4.The densities of spatial distribution of the NE and the NW faults supplement to each other,indicating the inter-restraint properties of these two groups of faults.Eventually,correlating the isoline maps of fractal dimensions and historical earthquake distribu-tion,it is tried to find out the relationship between the fractal characteristics and seismic activities.
