This paper selects the observations data of a total of 34 continuous and stable water temperature,using the aomalous process and subordinate function analysis method to extract abnormal jointly and analyze the relationship between water temperature and the MS≥5.0 earthquakes. The results show that the single anomaly extracted by this method has short-term implications and good relationship with earthquake,but increased the omission rate of earthquake; The groups anomalies in Yunnan Province extracted by anomaly frequency and weight integration method have obvious correspondence with MS≥5.0 earthquakes,which reduce the omission,and can pass the R-value inspection of a confidence level of 97.5%; After Yunnan region has been divided into different areas by tectonic and seismic activity,we extracted small area groups anomalies.Only considering earthquake at the same area,then the omission and false rate of earthquake significantly increased in each area; Analyzes its reason,we found that the water temperature anomaly and earthquake are the products of increasing regional tectonic activities,and the water temperature shows a better characteristics of increasing regional tectonic activities,and the earthquake will occur easily based on increasing regional tectonic activities,therefore regional groups anomalies have more correspondent potency; The temperature abnormity extracted by using the anomalous process and subordinate function analysis method shows the characteristic of accelerated water temperature before earthquake,and regional groups anomalies can be used as short-term time indicators of the earthquakes( MS≥5.0)in Yunnan region.
