广东省主要活动断裂的分形特征及其与区域历史地震活动的关系
Fractal Analysis of the Main Active Faults and Its Relationship with Regional Historical Seismic Activities in Guangdong Province
摘要
Abstract
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.关键词
