| 摘 要： | 收集了我国南北地震带地区1970年~2012年的85次地震事件的烈度等震线资料，建立了震中烈度与震级之间的经验关系，利用长轴和短轴椭圆模型拟合得到了该地区的地震烈度衰减关系。同时还搜集整理了近年来基于我国各地区的地震资料，研究得到的地震烈度衰减关系，并将其中与南北地震带存在地域重合的研究结果与本文结果进行对比分析。该研究结果能够较好地反映南北地震带地区的地震烈度衰减规律，对该地区的地震灾害快速评估具有一定的参考意义。

| Abstract: | Isoseismal maps of the 85 earthquake events from 1970 to 2012 in the north-south earthquake zone of China were collected. Using these data, the empirical relationship between the epicenter intensity and magnitude was established. The long and short axial ellipse model was used to obtain the seismic intensity attenuation relationship in the area. At the same time, the seismic intensity attenuation relationship obtained based on the seismic data in various regions in China during recent years was also collected and discussed, and the results of the regional overlap with the north-south seismic belt were compared with the results of this study. The research results in this paper can better reflect the law of seismic intensity attenuation in the north-south earthquake zone, and have significantly meaning to the rapid assessment of earthquake disasters in this area. |
