摘　　要：讨论了民乐盆地及邻近地区的历史和现今强震活动的分布、大地电磁测深重复观测与现今强震发生的关系．结果表明，视电阻率曲线的系统变化与周围地区强震的发生有一定的对应关系。Distribution of strong earthquakes in and around the Minle basin and relationship between repeated MT observations and occurrence of strong earthquakes are discussed.The results show that systematical changes of apparent resistivity curves correspond to occurrence of strong earthquakes in the region,and ststematical variations of apparent resistivity with different frequency bands are closely related to occurrence of earthquakes with different strengths.
