在研究应用模糊地震学和统计地震学某些方法的基础上，通过实际预报检验，对一些中短期预报较好的方法，如地震活动平静异常μｑ 值，自相似从属函数μｓ 值，自助统计方差σＢ 值进行深入研究，探索孕震后期地震活动图像演化特征。结果表明：μｑ、μｓ、σＢ 值能够较好地反映地震前中短期异常变化特征，可以作为中短期预报定量化指标；空间时序图像系列的显示，能定性反映震前异常区域及地震活动图像演化特征。 Based on the study of some methods of applying fuzzy seismology and statistical seismology, some methods of medium and short term prediction, such as μq value of seismostatic anomaly, μs value of self-similar subordinate function, self-statistical statistical variance σB values ​​in-depth study to explore seismic seismogram evolution characteristics of late earthquake. The results show that μq, μs and σB values ​​can well reflect the characteristics of short-term anomalies before earthquakes, which can be used as quantitative indicators of short-term and long-term forecasts. The display of spatial time series of images can qualitatively reflect the anomalous regions before earthquake and the evolution of seismic activity images feature.
