摘要
Based on magnetotelluric data of Luzong area of Anhui Province,the authors studied the effects of various interference noises on magnetotelluric sounding data.The results show that the geological noise generally affects the whole frequency domain,the near-field interference mainly affects limited frequency of the high frequency,and the instability of the large power electric system mainly affects low frequency.Some suggestions are put forward for eliminating or reducing various kinds of noise interference.
