摘要
通过云南地区17个曾经发生过的地震烈度资料,用阻尼最小二乘法解超定方程组的方法获得了17个地震的震源加速度,更重要的是用此方法反演了云南地区的Q值分布,这对分析该地区的地质构造状况具有重要的参考意义。通过对结果的分析,发现Q值的分布与地震活动存在着相关关系。
Overdetermined equation is constructed by recorder of intensity of earthquake that hap-pened in seventeen regions of Yunnan ,accelerations of seventeen soureces of the earthquakes are ob-tained from solution of the overdetermined equation by method of damped least square. The more im-portant is that in this way the distributions of Q values in region of Yunnan is obtained in conversion ,and it is also important to researches both in geological situation there and in correlation between dis-tributions of Q values and seismic activity there.
