| 摘 要： | 以压磁效应为基础，运用地震多源场理论，对１９８８年至１９９３年发生在沂水、莒县附近的地磁场异常变化进行了初步的分析研究。认为，应将沂水、莒县附近的３个不同的地磁场变化形态作为一个整体，地磁场的变化受构造控制，是由基本应力场作用下北西向沂源－沂水断裂产生的继承性左旋张扭运动所引起。

| Abstract: | Based on the Piezo-magnetic effect,this paper haS shown some prehminary analysis and study about anoma1ous change of the geomagnetic fie near Yishui-Juxian areafrom l988 to l 993 by using the theory of muIti-so-urce field of seismic process. Weconrider that three different change forms of the geomagnetic field near Yishui-Juxianarea should belong one system,and be controled by tectonics,and were caused by succes-sive left-lateral slip of the northwestern Yiyuan-Yishui fauIt. |
