摘　　要：详细介绍榆树地震台地电场观测系统的运行状况,从数据完整率、静日、扰日变化形态以及相关系数、差值等方面对观测系统运行进行综合评价,结果表明:榆树地震台地电场观测系统运行稳定可靠,能够记录到震前地电场异常变化,可以为地震预测预报研究提供一定依据。In this paper, the operation status of geoelectric field observation system at Yushu Seismic Station is introduced in detail and the comprehensive evaluation from the aspect of data integrity rate, morphological changes, static disturbed days and correlation coeffi cient, interpolation on the observation system. The results show that observation system of geoelectric fi eld at Yushu Seismic Station runs stable and reliable, and is able to record abnormal changes of geolectric fi eld before the earthquake, can provide the basis for earthquake prediction study.
