| 摘要: |
| 根据安徽省历史地震(294～1969年，M≥4?)和现代地震(1970～2013年，MS≥3.5)资料的统计结果，通过估计历史地震序列类型，将安徽地震类型划分为“相对安全类”和“相对危险类”。结果表明：安徽省历史地震类型的统计结果和空间分布特征与现代地震序列类型大致吻合，绝大多数中强历史地震属“相对安全类”，而“相对危险类”的历史地震主要分布在霍山地区、皖东北地区和宿北地区。安徽地区内的地震活动具有较高的继承性，研究结果可为该区域震后地震趋势的快速判定提供参考。 |

| Abstract: |
| According to the statistical results of historical earthquakes(294～1969，M≥4?) and modern earthquakes(1970～2013，MS≥3.5)in Anhui Province，the paper，by estimating the types of historical earthquake sequence，divides the earthquakes in Anhui into the comparatively safe class and the comparatively dangerous class. The results showed that the historical earthquake classes and the characteristics of spatial distribution in the Anhui region accord with those of modern earthquake sequence. The majority of historical strong earthquakes belong to “comparatively safe class”，and historical earthquakes of “comparatively safe class” are mainly located in the Huoshan area，northeast area of Anhui and northern area of Suzhou city. It can be concluded that the seismic activity in the Anhui region has higher inheritance，and the results from this study can provide a reference for the regional quick post seismic tendency judgment. |
