| 摘 要： | 为了比较全面的反映首都圈地区地震活动性的各方面特征，利用地震活动性总体状态参量Rt值方法，跟踪并分析首都囤地区ML≥5．1地震前的地震活动状态。研究结果表明，当Rt〉0．60时，首都圈地区地震活动状态稳定；当Rt≤0．60时，则表明首都圈地区地震活动处于不稳定状态。同时，对Rt值的地震预测能力进行了检验评估。

| Abstract: | In order to more fully reflect all aspects of the characteristic of seismicity in the Capital Circle Region, an integrated parameter Rt of seismicity was used to routinely analyze the seismic activity before ML≥5. 1 earthquakes occurred in the Capital Circle Region. The result shows that when Rt〉0. 75, the seismic activity is stable in the Capital Circle Region, while Rt≤0.75, the seismic activity of the Capital Circle Region is unstable. At the same time, the efficiency of earthquake prediction by use of Rt parameter has been estimated. |
