摘　　要：龙门山断裂带上2008年四川汶川8.0级地震和玉树-甘孜断裂带上2010年青海玉树7.1级地震前,地处鲜水河断裂带的四川甘孜地震台的温泉、姑咱地震台的海子泉、道孚甲宗乡53温泉、康定二道桥温泉地下流体测项有明显的前兆异常。其异常特征表现为破年变规律,存在短临异常,也有1—2年的中期异常。Before the Wenchuan 8.0 earthquake in 2008 at Longmenshan fault zone and Yushu 7.1 earthquake in 2010 at Yushu--Ganzi fault zone, there have obvious abnormal of the under- ground terns source of the fracture passageway is shutting state of Ganzi hot spring.Guzan Haizi spring.Daofu Jiazongxiang hot spring and Kangding Erdaoqiao hot spring in the Xian- shuihe fault zone. The abnormal feature has break annual variation.short face abnormal and 1--2 years interim abnormal.
