用历史地震影响烈度进行安徽烈度区划研究

建立了安徽79个市、县历史地震影响烈度目录，并利用其统计特征进行烈度区划研究．结果表明：在中等强度地震区及所利用的烈度资料分布区间相对较窄的情况下，仍可用历史地震影响烈度分析方法进行烈度区划。与“中国地震烈度区划图（1990）”安徽部分对比，两者概貌大致相同，但也有所差异，都从不同角度反映了未来地震危险性的区域特征。

RESEARCH ON INTENSITY ZONING IN ANHUI BY THE USE OF DATA OF HISTORICAL EARTHQUAKE AFFECTED INTENSITY

In this paper, we set up the historical earthquake affected intensity catalogue of 79 counties and cities of Anhui province. The intensity zoning research is made by using the statistic characteristics. The results shows that this method of intensity zoning research is feasible for the area where earthquake intensity is moderate and the interval of intensity distribution is relatively narrow. The configuration of the map given in this paper is similar to that of Seismic intensity Zoning Map of China (1990), though it is little different. They show the regional characteristics of future seismic risk from different angles.
