Evaluation of the Lawn Field Observation System in Lixian County，Gansu Province

Briefly describe the observation overview of the lawn electric field in Lixian County, collect observation data for graphical analysis, compare and measure the parameters of observation quality (correlation coefficient and difference), and draw the conclusion that: 1) the newly established observation system operates well and produces high-quality data internally; 2) Two observation systems simultaneously observe without interfering with each other; 2) Can receive external abnormal information (such as geomagnetic storms); 3) The main observation system (solid non polarized electrode measuring point 2) has better correlation; 4) This article can serve as a reference for electrode layout and electrode selection in the observation of ground electric fields at other stations.
