摘要
本文利用山西地区的地震地质、地质构造、地震活动性、地球物理场等特征资料,对有关特征进行了图象识别,采用综合决策方案以提高识别的稳定性。综合判定结果分析表明,在研究区内的180个对象中,得到54个D类对象,占全部识别总面积的30％,其中向31个对象,历史上已发生过6级以上强震或在强震附近,另有23个对象为新判定的6级以上强震潜在震源区。得到山西强震潜在震源的预测图。
From the data of seismogeology, geologic structure, seismicity and geophysical field the pattern recognition has been made on the concerned characteristics,and the synthetic decision method has also been used to improve the recognition stability. The synthetic analysis results indcate that out of 180 cases in the study area 5.4 belong to D category, making up 30 percent of the entire area. Among those cases 31 are in the place where or nearby strong events over magnitude 6.0 occurred in the history, and 23 are regarded as potential source regions of strong events (M>6.0). The potential strong event source region in Shanxi is thus obtained.
