摘　　要：2003年4月17日德令哈发生6.6级地震,2004年该震区相继发生了5次5级以上的中强地震,分析德令哈系列地震前青海省水氡资料,发现震前水氡异常较显著,并表现出不同的异常特征。It is occurred a Ms 6. 6 earthquake in Delingha on Apr. 17, 2003, and later five times Ms≥5.0 earthquakes occurred again in the same area in 2004. The radon data in Qinghai province became abnormal before these earthquakes, and the anomalous characteristics were quite different.
