摘　　要：通过对不同野外工作时间获取的音频大地电磁测量数据的对比分析,总结了天然电磁场的特点及最适宜开展音频大地电磁法野外工作的季节。最后,指出了采用人工信号源弥补天然电磁场弱信号的有效性。By comparing and analyzing audio magnetotellurics （AMT） data measured of different pe- riods in nearly one year in field, we summarized the character of natural electromagnetic signals and the best season to perform AMT survey. It was emphasized that the validity to use man- made sig- nals was valid to make up the weakness of natural electromagnetic signals.
