摘　　要：针对地震区域间的关联研究这一问题,将历史地震的时序信息引入进来,根据历史地震所伴随的地震异常以及其时序信息建立复杂网络模型.将每个地震区域看作网络节点,根据幂级数展开得到每个网络节点的灾害系统动力学方程,并利用压缩传感理论求出网络节点之间的关联系数,从而构建地震区域的网络拓扑图.实验结果表明,利用压缩传感理论将时序信息转化为复杂网络不仅具有可行性,并且还可以在少量信息的基础上精确恢复关联信息.Aiming at the earthquake regional-related issues,the time series of historical earthquakes were put forward in this paper. The complex network model was built according to the seismic anomaly and time series of the historical earthquakes. Each seismic region was regard as network nodes,then the disaster system dynamic equations of network nodes were obtained through the power series expansion,and the correlation coefficients between network nodes were obtained through the compressive sensing theory,so as to construct the network topology of seismic regions. Experimental results show that the converting timing information into complex networks on the basis of compressive sensing theory is not only feasible,but also can recover the correlation information precisely by small amount of information.
