| 摘 要： | 绥化地电阻率已有二十二年连续观测资料，利用绥化1992年-2001年电阻率十年观测资料与嘉荫即黑龙江省发生4级地震较集中的地区，北纬47°30′-49°00′东经128°30′-131°00′区域4级以上的地震对比分析可知，该区1992年-2001年共发生4级以上地震11次，具有成组发震的特征，在地震发生前绥化地电阻率观测资料N45°W月均值有阶式变化，而在地震发生后绥化地电阻率观测资料N45°E月均值有相同形态变化。

| Abstract: | Suihua earth resistivity observation has already been set up for 22 years data （1992 to 2001 ） with the above 4 magnitude earthquakes which focus years.We compared ten in Jiayin of Hei longjang province （northe latitude： 47°30′ - 49°00′; east longitude： 128°30′-131°00′） . The M〉4 earthquakes happened 11 times, and happened in group. We found stepped variation, in the monthly mean values of earth resistivity （N45°W） before the earthquakes, And after earthquakes they had the same shape variation. |
