Abstract: Based on processing and analysis of the minute value data of geoelectric field at many stations in the recent years, we get some preliminary cognition of the basic characteristics of the geoelectric field. At the different stations we can record the same variation shape of the telluric field in quiet days, disturbed days and geoelectric storm days, but the variation ranges differ from each other.Variation of data in long and short polar distances at one station is well correlated, and variation of data in the same direction at the different stations is well correlated too. The azimuth angle of telluric field at different stations shows the consistent variation shape. The polarization direction angle at different stations also shows the consistent variation shape during geoelectric storm days. By the effect of local natural electric field, variation of telluric field at some stations is disturbed.
