摘　　要：整理朔州井水位自观测以来的资料,对影响井水位动态变化特征的主要干扰因素进行分析,结合剔除干扰后的资料,分析山西北部4级以上及晋冀蒙交界区5级以上地震前朔州井水位变化特征,得出该井震前异常特征及判别指标,给出预测效能R评分值。By sorting out the data of Shuozhou well water level since the observation,the main interference factors affecting the dynamic change characteristics of well water level are analyzed,and the variation characteristics of Shuozhou well water level before M4 earthquake in the north of Shanxi(including Shanxi-Hebei-Mongolia border area)are analyzed combined with the data after removing the interference.The abnormal characteristics and discriminant indexes before the earthquake are obtained,and the R score value of prediction efficiency is given.
