| 摘 要： | 利用中国、哈萨克斯坦、吉尔吉斯斯坦天山地区较丰富的地震等震线资料，在同一个统计单元进行统计分析，得到了天山地区的地震烈度衰减规律。所得到的地震烈度衰减曲线与实际资料吻合较好，以此衰减关系进行天山地震区划计算，结果较为理想，同时，把此衰减规律与西北地区及新疆地区烈度衰减规律的衰减特征做了对比分析，指出了天山地区烈度衰减规律的相对独立性

| Abstract: | The isoseismic data in the Tianshan area are ample. Through comparing them it is found that whether within or beyond the bondaries of China,the characteristics of seismic intensity attenuation and isoseismal identifying methods are very close in this area.So the whole Tianshan area is taken as a statistical unit and analysed,the regularity of seismic intensity attenuation in the Tianshan area is gotten.The intensity attenuation curve tallies with the actual data.Using this attenuation relation to calculate Tianshan seismic regionalization the result is better.But after comparing it with the seismic intensity attenuation regularities in Northwest and Xinjiang areas,it is thought independent relatively. |
