利用２ 个描述强震前中短期阶段地震活动异常平静及丛集的参量，计算了新疆地震区１９７０～１９９８ 年以１ 年为窗长、３ 个月为步长的地震活动异常图像，并给出了发生在新疆乌恰的２ 次７．４ 级地震前后，新疆地区σＮ 异常分布动态演化图像。对异常图像的动态演化过程与强震发生地点的关系进行了分析；对将其用于新疆地区地震预测进行了预测检验。结果表明：该参量能较好和直观地描述中强震前地震活动异常时空动态图像，不受样本量的限制，并能给出未来发生强震的可能地区。该方法在预测新疆发生强震危险区方面有较好的效果。
Using two parameters describing the anomalous seismogenic anomaly and clustering in the middle and short periods before strong earthquakes, we calculated the anomalous seismic activity anomalies in the seismic region of Xinjiang Province from 1970 to 1998 with 1 year as the window length and 3 months as the step length. The dynamic evolution of σN anomalies in Xinjiang before and after the MS 7.4 MS 2 earthquake in Wuqia, Xinjiang, China. The relationship between the dynamic evolution of anomalous images and the place where strong earthquakes occurred was analyzed. The prediction of the earthquake prediction in Xinjiang was carried out. The results show that this parameter can describe the spatial and temporal dynamic anomalous seismic anomalies before and after moderate-strong earthquakes well and intuitively, without being limited by the sample size, and can give possible areas for future strong earthquakes. This method has a good effect in predicting the occurrence of strong earthquakes in Xinjiang.
