根据对张北－尚义地震宏观异常的震后现场调查结果，统计了各类宏观异常的异常数量与主要表现形式，分析了宏观异常的时空分布特征，在此基础上探讨了宏观异常的形成原因及其对地震短临预报的意义。
Based on the survey results of the post-earthquake macroscopic anomalies in Zhangbei-Shangyi earthquake, the number of anomalies and the main manifestations of various types of macroscopic anomalies are statistically analyzed. The temporal and spatial distribution of macroscopic anomalies is analyzed. Based on this, the formation of macroscopic anomalies Reason and its significance to short-term and short-term earthquake prediction.
