摘　　要：浙江省及其周边的历史震例资料稀少,其地震烈度衰减关系一直沿用中国东部地区的地震烈度衰减关系模型。本文采用椭圆模型,利用浙江及邻区历史地震的震害资料,建立了浙江及邻区天然地震烈度衰减公式。根据东南沿海地区水库地震多发的特点,收集整理了水库地震相关震例数据,建立了浙江及邻区水库地震烈度衰减公式。最后,将本文拟合结果与其他学者拟合出的衰减模型通过实际震例进行了对比,并进行了相关讨论。The seismic intensity attenuation relationship is important not only for rapid earthquake assessment but also seismic risk evaluation. In this article, historical earthquakes in Zhejiang and its surrounding areas were carefully analyzed at first time; and then the intensity attenuation relationships of Zhejiang Province and its surrounding areas were established. In addition, by studying the historical reservoir induced earthquakes, the intensity attenuation relationship of reservoir-induced seismicity in Zhejiang and its neighboring areas were established. At last, we discuss applicability of the results by comparing them with the disaster survey and models developed by other researchers.
