摘　　要：分析了由于观测系统故障、电阻率测量、雷电、降水及人类活动等因素,造成地电场观测资料质量降低的客观现象,并对地电场观测各物理量之间的关系进行相关论证,提出异常分析方法,结果表明:新沂台地电场观测数据能真实反映观测场地的客观变化,排除各类影响因素,其观测精度很高。This paper analyzes interference factors in geoelectric field observation, such as observation system fault, electric resistance measurement, lightning, precipitation and human activities. These interference factors can lead to data quality decreasing. Relationships between each observation items are also discussed and method to discern anomaly is put forward in this paper. The results indicate that observation data in Xinyi station can reflect the actual change of the observation site; if the interference factors can be eliminated, the precision of the data is quite high.
