为了研究地震网络的动力学行为，基于时空影响域的地震网络，分析以大地震发生时间为基点的网络的拓扑特征演化。结果发现：大地震发生前网络的规模和熵值较小，模块度较大；大地震发生后网络的规模变大，熵值跳变到相对大的值，模块度值达到极小值。同时分析了1992年地震网络的多参数拓扑特征演化，结果表明地震网络表现出一种内在的网络动力学行为。此外，发现从大地震发生前100 d 开始网络模块度振荡出现极大值，熵值振荡出现极小值，并呈现很好的负相关性。

Based on the earthquake network of the time-space influence domain,the topology of seismicity around the main shock was analyzed for the network's dynamic behaviors.It was found that the scale and the entropy were small while the modularity was big before the main shock;the scale increased greatly,the entropy jumped to a high value and the modularity reached a minimum value after the main shock.Meanwhile,the multi-parameter evolution of the topology of seismicity in 1992 was analyzed,whose results showed that the earthquake network exhibited a inner dynamic behavior.In addition,the modularity took a maximum value,the entropy had a minimum value,and they presented good negative correlation.
