| 摘 要： | 完善了累积危险度的强震危险地点跟踪预测方法，并对１９８９看以来首都圈及邻近地区累积危险度的演化进行了分析。结果表明，累积危险度的演化过程，反映了地震孕育及构造应力活动的过程；２次６级地震前，均出现累积危险度数值增大，震后扩散－消退；累积危险度高值区及其边缘地国可能发震地点。

| Abstract: | In this paper,a tracing prediction method of risk sites of strong earthquakes by using the accumulation risk dimension has been improved and the evolution of the accumulation risk dimension in the Capital Circle and its neighboring areas since 1 989has been analyzed. The evolution process of the accumulation risk dimension reflects the course of earthquake preparation and tectonic stress activity. The value of the accumulation risk dimension increased before the two earthquakes whose magnitudes are greater than 6and decreased after the earthquakes. The high value area of the accumulation risk dimension is the potential earthquake occurrence site. |
