摘　　要：利用多种方法对山东定点形变台站资料进行了系统处理，并分析了其与山东及沿海中强地震的关系。结果表明：山东形变台可监测到台站100～250km内中强地震的异常变化，其中各类分量异常及γ因子异常一般为中短及短期异常，而固体潮畸变为临震异常。The authors systematically analysed the data of fixed deformation stations in Shandong province using some methods,and the results show that anomalous variation of medium-strong earthquakes in 100～250km can be observed by the fixed deformation stations in Shandong area,the abnormals of component and D factor can be regarded as middleshort and short term anomalies, and the solid tide distortion as impending earthquake anomaly.
