摘　　要：分析了2016年1月至6月重庆地震台网数字记录的巫山机场人工爆破波形资料,认为爆破事件的时空强具有明显规律性,其P波初动震相、A_S/A_P振幅比、频率谱等特征与天然地震具有明显区别,为正确识别重庆地区人工爆破和天然地震具有参考价值。The paper analyzed wave data of blasting events recorded at Wushan airport by Chongqing seis- mological network between January and June 2016. The results show that the time-space-strength distribu- tions of blasting events have obvious regularity, and the initial motion of p wave, Ap/As amplitude ratio, frequency spectrum etc. of blasting events is obviously different from natural seismic waveform. The re- sults can provide some reference for the judgment of earthquake and explosions signal.
