摘　　要：按照《地震及前兆数字观测技术规范》和《地震台站观测环境技术要求(第二部分,电磁观测)》(GB/T 19531.2-2004),对安徽省肥东地震台地电阻率观测场地进行了勘选,采用十字电测深法勘探地下介质的电性结构分布情况,并对观洲环境进行电磁骚扰测试.经过对测量结果进行计算和初步分析处理后,认为该场地适合地电阻率台站建设。In accordance with The technical specifications of earthquake and its precursor observation ,technical requirement for observation environment of seismic stations Ⅱ.Electromagnetic Observation（GB/T 19531.2-2004）, careful survey were undertaken upon the geo-resistivity observation sites in Feidong Seismic Station. Using the cross electrical sounding method, the distribution of underground medium electrical structure was explored and the observation environment were test on source of electromagnetic disturbance. After calculating and initial analyzing, the survey results show that the site was available for the construction of geo-resistivity stations.
