选取江苏数字地震台网记录的部分天然地震与人工爆破波形数据，通过波形对比分析、震幅比以及频谱等方面的对比发现两者之间不同之处。把这些不同的方法应用到数字地震台网实际工作中，能够快速有效地分辨出天然地震和人工爆破，为今后震相的识别提供可靠依据。

The crux of rapid reports of earthquakes is to establish three factors of the event as soon as possible.Seis-mic phase analysis is the basic work of earthquake monitoring,yet all types of seismic phase demand correct inter-pretation to determine the earthquake epicenter within the network.Summarizing rapid treatment methods can im-prove seismic phase analysis and the speed of issuing the rapid report.The present situation of rapid reports of earth-quakes in Jiangsu province is analyzed from the viewpoint of both science and society,with recognition of its develop-ment.On this basis and using waveform data recorded by the Jiangsu digital seismic network,we studied the differ-ence between natural earthquakes and explosions by contrasted comparative analysis of the waveform,amplitude,fre-quency spectrum,and other aspects,and found a difference between earthquakes and explosions,both in Jiangsu and adjacent areas.These methods,applied to digital seismograph network practice,can quickly and effectively differenti-ate natural events from artificial explosions.As a quick distinguishing method,it represents a swift and proficient ap-plication during major earthquakes,which provides a reliable basis for the identification of future phases.
