摘要
分析了阳原台地电阻率ρ＿ｓ年变化的特征及其原因，研究了该台１９８９年后ρ＿ｓ年变幅增大的诸种可能因素，认为大同６．１级地震前后地震活动增强是引起ρ＿ｓ年变幅增大的主要原因。
The features and its reasons of annual variation of the earth resistivity(ρ_s)in Yangyuan station are ana-lyzed, and various possible reasons of the annual amplitude accrete of ρ_s after 1989 are discussed,suggestedthat the seismicity enhancement before and after Datong earthquake of M=6.1 is the principal reason of theannual amplitude accrete of ρ_s.
