摘要
基于成都台长期的地电阻率观测数据在时域的变化规律，对该地区观测数据的正常变化特征、干扰因素、可靠性进行分析研究，获取观测数据的动态特征。同时通过成都台地电阻率观测数据在汶川MS8.0、芦山MS7.0等地震前后的变化动态，研究地电阻率观测数据在灾害性地震前后的趋势性及短临异常特征，并对其进行映震分析。分析表明：视电阻率的异常变化与Ms7.0以上强震的发生存在一定的映震关系。
Abstract
Based on the earth resistivity variation regular in time domain and frequency domain,and the long-term earth resistivity observation data of Chengdu station, analysis on the normal variation , interference factors, reliability of observation data,to acquire dynamic characteristics of earth resistivity. as well, analysis on the variation before and after the Wenchuan MS8.0 and Lushan MS7.0 earthquake of observation data, the tendency and anomaly characteristics. The analysis shows that: anomaly characteristics of earth resistivity and earthquake have a relationship,it’ s more obvious when a strong earthquake happened.
