摘　　要：根据川滇２０例Ｍ≥６７级强震前中短期地震活动图象异常的分析对比，归纳出８项有普适性的图象异常指标，试图对一、二年内各个强震区（１００×２００平方千米）强震孕育程度给出一个经验性的估计量。并将它作为中短期强震预报的基本依据。同时，这些异常的动态既是改进年度性震情会商的着眼点，又是震情跟踪的具体目标。Based on the comparison study for the medium to short range anomaly of seismicity image of twenty seismic events( M >=6 7) before several strong earthquakes, eight anomaly indexes of seismic image for general purpose are summarized. We want to give out a statistical indexes to predict the preparation degree of coming earthquake with 1～2 years and take these indexes as a start point for our prediction of earthquake.
