摘　　要：在山西大同—阳高 1989年 6 .1级地震的震例总结中 (张肇诚 .中国震例 .北京 :地震出版社 ,2 0 0 0 ) ,共收集了 2 7项地下流体异常 ,经过对资料的整理研究 ,又发现了 2 0项。以这些异常为样本 ,研究了异常场的形态组合、空间展布与时间演变等特征 ,指出水位动态异常以下降型为主 ,水化异常以上升型为主 ,异常呈条带分布 ,是场源共同作用下形成的。In the sum up about earthquake examples for Datong Yanggao earthquake of M6.1 in Shanxi,27 items of anomalies in underground fluid were collected. 20 new anomalies are found after more detailed analysis to the data. Taking these new anomalies as samples ,the characteristics of abnormal field in morphological combination ,spatial distribution and time evolution are studied.The results show that the dynamic anomaly in water level is mainly show itself in falling, mean while the anomaly in water chemistry is mainly in rising. The anomalies distribute in strip, which is formed by co action of field sources.
