摘要
应用综合信息函数的理论和方法 ,根据形变观测点的空间非均匀分布和首都圈地区几次强震前形变场的变化规律 ,考虑各测点的不同地球物理性质 ,利用近 2 0年来的形变资料 ,计算了首都圈及邻近地区 1 995年以来的综合信息函数值 ,动态地显示了在局部区域内中强地震前 ,形变异常的演化特征。
According to the non uniform space distribution of deformation surveying spots and the deformation abnormal change before the strong earthquake in capital circle area,the recent 20 year′s data are calculated by means of information function in this paper.The information function value is abtained since 1995.Finally,the evolution features of deformation abnormality in different surveying spots are analyzed before strong earthquake.
