| 摘 要： | 建立适合本地区的地震烈度衰减关系,是研究地震背景的重要一环。随着资料积累的增加和人们认识的提高,我们在分析历史资料完整性、可靠性基础上,筛选21次有详细宏观调查报告、有仪器测定震级,震级、烈度分布均衡的54组数据。采用最小二乘法,变换常数R,反复统计、搜索方差小,结果符合客观规律的统计结果,并与原东部和华南地区的衰减关系进行全面的比较。建立更符合客观规律,适合本地区的地震烈度衰减关系。

| Abstract: | To set up the seismic intensity attenuation relationship suitable for this region is a important tache for researching seismic background. Along with the accumulation of data and recognized enhance, on the basis of analyzing history data integrality and reliability, we filtered 21 times, 54 set of data which have determinated magnitude by instruments and magnitude-intensity distribution balanced. Adopting least-squares method and changing constant R and repeatly statisting and searching the statistic results which possess smaller square error and accord with external law as well as comparing with the attennuation in eastern and south china region to set up the intensity attenuation relationship more accord with external law and more suitable for the region. |
