摘要/Abstract

摘要： 基于时空影响域方法构造地震网络，结果显示地震网络具有小世界、无标度等复杂网络的一般特征.选取1990年至2010年的四川地震数据进行研究，这些地震大多分布在龙门山断裂带上.对所构造的地震网络进行节点汇聚，得到以节点为单位的地震序列，序列类型为前震-主震-余震型.通过对地震序列的能量变化进行研究发现，能量的变化不具有周期性，而一定大小的时间窗口内的地震能量和的变化具有周期性，且能量中心分布在龙门山断裂带的主中央带上.这些结果说明，基于节点汇聚的地震序列分析方法对于认识地震的发生规律具有重要的意义.

关键词: 地震网络, 龙门山断裂带, 节点汇聚, 地震序列, 能量规律

Abstract: Based on space-time influence domain， an earthquake network was built， which had small-world and scale-free characteristics of complex network. The Sichuan seismic data were chosen between 1990 and 2010， most of which distributed on the Longmenshan fault. After node converging on the earthquake network， several seismic sequences from nodes were obtained， which mainly belonged to foreshock-mainshock-aftershock type. Through studying the energy changing of seismic sequences， the results indicated that a single earthquake’s energy changing does not show the law， but the sum energy of sequences with a certain size time window has periodicity change， and the energy center distributes on the Longmenshan central fault zone. All of these researches show that there is an important significance to recognize the regularity of earthquake using analysis method of seismic sequence based on node converging.

Key words: earthquake network, Longmenshan fault, node converging, seismic sequence, energy law
