| 摘 要： | 讨论了地球岩石圈的自组织临界状态和地震发生的非局域性与多重标度分形统计特征。研究了地震多重分形性质的计算方法及其应用于地震预报的前景。采用推广ＧＰ算法从典型震区的地震数据计算地震多重分形分布的广义维数谱和奇异性谱以确立较敏感的强震前兆，对于不同算法进行了精度、数据量要求及适用范围的比较。研究结果表明：地震分布的多重分形维数谱和奇异性谱对于一些典型震区的强震发生具有中期预报价值。

| Abstract: | In this paper, the multi fractal statistical characteristics of earthquake distribution are summarized. The calculation method of earthquake multi fractal features is presented, and the possibility of its application to earthquake prediction research is studied. The generalized Grassberger Procaccia algorithum is used to calculate multi fractal property of earthquake spatial distribution. The results show that the medium term symptoms of strong earthquakes in some regions can be proposed from the multi fractal dimension spectrum and singularity spectrum of earthquake distribution. |
