收集整理大地电场观测的各类干扰及变化原因，通过详尽的调研和相关分析研究，提出其常规干扰变化的识别方法，以及为提高大地电场观测资料的质量而采取的干扰抑制技术，并针对各类干扰源的机理，改进和完善现有的大地电场观测技术，提高资料的稳定性和可靠性。

Based on the investigation of diversified interferences occurred in geoelectric observation and theirs reason, since this method has been operation during “the ninth fiveyear plan”, the methods for recognizing and suppressing the routine interference variety in geoelectric observation data are presented in this paper. According to the mechanism of interference source, the existing geoelectric observation technique is ameliorated and perfected. The stability and reliability of geoelectric observation data are much improved.
