| 摘 要： | 应用东北三省及内蒙古东部地区的12个地磁台站总场强度整点值资料,利用空间相关法研究了总场强度数据与黑龙江及邻近地区中强地震的关系,给出了该方法在黑龙江地区的异常参数,统计了黑龙江省及邻区地区2008年以来发生的级地震前的地磁空间相关异常的次数,对震前异常进行了系统的统计和分析,发现震前空间相关法都有较好的映震效能。

| Abstract: | The application of the Northeast four provinces of 12 geomagnetic stations total field strength the hour data, using spatial correlation method was used to study the relationship between the total field intensity data and moderately strong earthquakes in Heilongjiang and its adjacent areas, gives the abnormal parameters of this method in Heilongjiang area, The number of the spatial level associated anomalies of precursory before the earthquake since 2008 of Heilongjiang province and its adjacent areas has been Statisticed, the statistics and analysis system, found that before the earthquake, the spatial correlation method has good reflecting earthquake ability. |
