| 摘 要： | 在地震危险性分析中，潜在震源区地震活动性参数的确定是关键的一环。为了不低估大地震的影响，恰如基分地将地震年平均发生率分配到带内各个潜在震源之内，准确确定地震带内发生Mj档震级的地震落在第i 个潜在震源区的概率是关键的一步。本文采用图像识别方法确定地震发生的相对概率，可以较客观地反映地震的时、空不均匀性，准确地确定地震带内发生Mj档震级的地震落在第i个潜在震源区的概率。

| Abstract: | In seismic risk analysis, determination of parameters of seismicity in potential focal area is a key step In order to correctly estimate the effect of earthquake and admeasuring the annual mean rate of earthquake occurrences to different potential focal areas of an earthquake zone, precisely determining the occurrence probability of earthquake with a range of magnitude Mj in the i th focal area in an earthquake zone is a linchpin In this paper, image distinguishing method is used to determine the relative probability of earthquake occurrence With this mehod, the nonuniformity of spatio-temporal distribution of earthquakes can be impersonally indicated and the occurrence probability of earthquake with a range of magnitude Mj in the i th focal region in an earthquake zone can be precisely determined |
