| 摘 要： | 利用新疆历史地震考察资料，采用多元回归方法拟合新疆地区地震烈度衰减规律。在重新整理烈度、距离等参数的同时，认为取两等震线的中心线比取烈度的外包线更合理。文中提供了点圆模型、椭圆模型的烈度减衰函数，还探讨了不同地震类型的烈度衰减规律，为进行加速度衰减规律的转换提供较为合理、可靠的依据。

| Abstract: | Combined with the survey data of historical earthquake in Xinjiang,the seismic intensity attenuation law has been fitted with multiple regression method. When reanalyzing the parameters for intensity and distance,it iS considered that taking the central line of the two isoseismic is more reasonable than taking the outer envelop of the intensity. Also,the intensity attenuation function of point source model and elliptical model was used to search for the intensity attenuation law for different types of earthquakes,which provides more reasonable and relisble evidences for the inversion of acceleration attenuation law. |
