| 摘 要： | 本文采用多分形的方法研究了四川西部地区20年来的地震活动的空间分布特征.对D_q谱与D_(-1),D_(-2)曲线结合震例进行分析,指出其变化与强震活动有密切联系。并结合空区理论,认为D_q(q<0)主要描述了地震空区的情况,该方法在地震前兆信息提取有中重要意义。

| Abstract: | The spatial distribution feature of earthquake activities in west of Sichuan since 1970 has been researched with the method of Multi-fractals in this paper. After analysing D_q spectrum, D_(-1) and D_(-2), curves,We pointed out that their changes related with strong earthquake events. Considering along with seismic gap theory,We concluded that D_q(q<0) peak values mainly reflected seismic gap. This methed is of important significance on the selection of precursory information of earthquakes. |
