In order to find out the distribution characteristics of the ground induced electric field in the Dabie orogenic belt during the geomagnetic storm, the magnetotelluric sounding data of the Dabie orogenic belt are introduced, and the geomagnetic field data of Wuhan geomagnetic station during the strong geomagnetic storm from November 7 to 9, 2004 are used to calculate the induced geoelectric field Frequency distribution. The results show that: during the geomagnetic storm, the amplitude distribution of electric field intensity in frequency domain is uneven, and some values are large; the amplitude of North-South component of electric field intensity in frequency domain is generally larger than that of East-West component; the frequency distribution corresponding to the maximum value of electric field intensity amplitude in frequency domain is relatively concentrated, and the frequency value is smaller, which is closer to DC. It can be seen that when the frequency is close to DC, the electric field with large amplitude will be generated, which will cause great interference to various artificial systems.
