摘　　要：基于区域地震构造环境、地震烈度分布、震源机制解,以及主震及余震的波形特征、频谱特征,分析了巴东5.1级地震的孕震构造背景。研究表明,该地震为在水诱发作用下产生的构造型地震。The seismotectonic background and genesis of Badong MsS. 1 Earthquake was analyzed based on the regional seismotectonic environment and main seismogenic structure. According to the comparison of distribution of intensity, focal mechanism solutions and seismic wave and spectrum of mainshock and aftershocks of the Earthquake with other earthquakes near by, especially Longhuiguan Ms5.1,1979, a conclusion can be drawn that Badong Earthquake is typical reservoir-induced and tectonic-type earthquake.
