将临汾中心地震台地电阻率EW测道电测深曲线 ,采用水平层状模型反演测区的电性结构 ,计算EW测道各层介质的影响系数 ,解释了地电阻率EW测道"夏高冬低"的年变现象.对地电阻率EW测向从2010年9月17日开始出现的趋势下降变化 ,采用褶积滤波法分析该区降雨和地下水位对地电阻率的影响 ,发现二者对地电阻率的影响都不显著.分析认为 ,当前存在的趋势异常变化是可信的 ,应密切跟踪此异常的发展变化.

Based on the electrical sounding data of earth resistivity of EW channel ,the electrical structure of the measuring region are inversed on horizontal layered model .The influence coefficient of each layer medium in under EW channel is calculated .Annual vari-ation of "Low in summer and high in winter"of earth resistivity in EW channel is interpreted .Influence of rainfall and groundwater level on the earth resistivity is analyzed by using convolution filter method to explain the downward trend of earth resistivity in EW channel from Sept 17th ,2010 .The results show that influence of both on earth resistivity is not significant ,so that the current trend of abnormal change may be meaningful and we should closely track its development .
