摘　　要：对德令哈6 6级地震前后前兆异常用常规分析方法和部分"十五"项目的阶段性成果进行分析研究,总结了此次地震前出现的前兆异常形态及特征,探讨了此次地震与昆仑山口西8 1级地震的关系。认为,在8 1级地震的影响下,外围区域应力场调整,地壳介质变化,是此次地震前地下流体出现异常较多、分布广泛的内在原因。Precursory anomalies before Delingha earthquake with Ms6.6 are analyzed by normal methods and other results,the precursory anomaly forms and characteristics are summed up in the paper.The relationship between this event and Ms8.1 earthquake is also discussed,and the results show that the outer regional stress field and crustal medium are changed,so many anomalies of underground fluid appeared before the event.
