Abstract：Based on the introduction to several widely-used methods for determining the magnetotelluric strike in the magnetotelluric depth probing exploration,the power spectrum file of the field measured EDI was used to calculate the strike,then the strike difference determined by different methods were analyzed and discussed,through filed example calculation,the influence extent of the strike on calculating apparent resistivity,phase and other MT response function were quantitatively reflected,the results show that the strike generally has obvious influence on apparent resistivity,phase and other MT response function.When the strikes lie in certain range,the strikes acquired by different methods have relatively small influence on apparent resistivity,phase and so on.
