摘要
This paper introduced the general situation of water temperature observation in Qinghai Province, analyzed the observation data. The study shows that before the Dachaidan Ms6.3 earthquake in 2008, short-impending anomaly appears in Golmud artesian well 160 km away from the epicentral area, meanwhile, the Dlingha still water well and the Tongren ground temperature, 130 km and 600 km away from the epicentral area, also show quasi synchronization short-impending changes. The form of the anomalies in the Tongren ground temperature and the Dlingha still water well are basic opposite except the beginning part, while the anomalies in the golmud well and delingha well are in the similar form of descending-ascending-stable-descending-recovering, which may indicate that there are differences between ground temperature anomaly water temperature anomaly.
