摘要： OFC模型通过模拟地震能量传递行为来认识地震的活动规律.为更加真实反映地震发生时的能量传递，用1992年美国加利福尼亚州地震数据抽象成的时空域网络替换传统二维规则网络OFC模型的底层网络.为了解仿真地震序列是否与真实地震数据具有相似性，将仿真地震序列网络化，与真实地震网络对比累积度分布的趋势，由此判断是否改进后的网络更接近真实地震网络.实验结果表明，时空域网络OFC模型产生的仿真地震序列和真实地震数据在宏观网络拓扑上具有一致性.

Abstract: The Olami Feder Christensen (OFC) model shows the law of earthquake activities by simulating the earthquake energy transfer behavior. In order to truly describe the earthquake energy transfer， the underlying network of the OFC model of regular two-dimensional network is replaced by the real time-space domain network extracted from the California earthquake data in 1992. The simulated earthquake sequence is constructed by the improved OFC model to find the similarity between the simulated earthquake sequence and real earthquake data. Whether the improved simulated network is closer to the real network is determined through comparing the cumulative degree distribution trend of the two networks. The experimental results show that， in terms of macro network topology， the simulated earthquake sequences are consistent with the real earthquake data.

Key words: complex network, earthquake network, OFC model, earthquake sequence, network topology characteristic
