摘　　要：通过对2017年以来金寨台4套地形变观测仪器记录到的所有地震进行统计分析,得出各仪器对于不同的地震存在不同的同震反应和形式;4套地形变观测仪器对远震和近震的记录能力有差异:垂直摆映震能力最强,能涵盖其他3套仪器所能记录到的所有地震,其次是水平摆、水管仪,映震能力最弱的是伸缩仪,对6级以上地震才有响应。Through statistical analysis of all earthquakes recorded by four sets of topographic deformation observation instruments at Jinzhai Station since 2017,it is concluded that each instrument has different coseismic response and forms for different earthquakes;the recording ability of the four sets of topographic deformation observation instruments for distant and near earthquakes is different:the vertical pendulum has the strongest seismic reflection ability,which can cover all earthquakes recorded by the other three sets of instruments,followed by the horizontal pendulum and water pipe instrument,and the extensometer has the weakest seismic reflection ability,which can respond to earthquakes above M≥6.
