摘要
本文利用现有各种地球物理资料、地震地质资料，探讨了重磁场特征、地壳结构、活动断裂与地震的关系，进而总结出地震震中在地壳介质中的空间分布规律。在此基础上建立了地壳稳定性评价分级指标，并对本区的地壳稳定性进行了评价。
Using various geophysical and seismogeological data available, the present paper has probed into relationship of characteristics of gravity and magnetic field, crustal structure and active faults to earthquake and summedup spatial distribution of epicenters in crustal media. On such a basis, the grade indices for appraisal of crustal stabilityis established, and an evaluation is made on crustal stability of this area.
