摘要

借助地震空区Ｒ－ｔ图分析原理，以新疆８次６级以上强震为例，分析研究强震前加、卸载地震的异常分布特征。结果表明：８次强震中有６次地震，震前在震中周围出现明显的加载地震相对集中分布或加载地震围空异常区，异常区出现于震前１年到１年半左右，其半径尺度为５０～９０ｋｍ。
Take eight M\-S>6 strong earthquakes in Xinjiang as earthquake examples,the anomalous distribution characteristics of loading and unloading earthquakes before the strong earthquakes have been analyzed and studied with the aid of analytical principle of seismic gap R-t map.The result shows that before 6 of 8 events,relatively concentrated distribution of loading earthquakes or anomalous gaps of loading earthquakes appeared around the epicenters obviously, and that the anomalous areas appeared during a period from one year to one and a half years before the strong earthquakes,the radii of which were 50～90 km.
