摘　　要：探索了用因子分析法识别地震孕育信息。结果很好地反映了共和等地震的孕育信息在震前及震后的演化过程，表明了地震活动性和前兆是同一地震孕育过程中不同阶段或同一阶段的不同表现形式。In this paper, the factor analysis method to identify the information of earthquake preparation is studied. The results reflect better the evolution process of the information before and after the main shock of the Gonghe earthquake and others. Meanwhile, it indicates that the activity and precursors are different form for distinct stage or same stage to one event, and gives the time mean of each factor. The study has certain practical value for earthquake prediction.
