运用新方法对苍山地震前后的形变资料进行了异常识别，重点分析形变异常的变化特征及机制。结果显示：①苍山地震是大面积应力积累、调整的结果；②以外围区100～200km中短及短期异常为主，而震中100km内的近源区异常并不显著；③进入短期的异常标志是中短期异常出现转折或反向。
The deformation data before and after the Cangshan earthquake were identified by using the new method. The changing characteristics and mechanisms of deformation anomalies were analyzed emphatically. The results show that: (1) Cangshan earthquake is the result of accumulation and adjustment of large area stress; (2) Short-term and short-term anomalies of 100 ~ 200 km in the outer area are dominant while the near-source anomalies within 100 km of the epicenter are not significant; Is the short-term abnormal turn or reverse.
