| 摘 要： | 在地下流体研究中，判定地下水异常的首要任务是区别地下水是受浅层物质补给的影响还是受深层介质活动的影响。本文通过对永清井及周边多次样品采集与测试，获得水化学组分和氢氧稳定同位素观测数据；通过对地下水样品数据对比分析、水化学组分及氢氧稳定同位素与大气降水线、水温数据分析，认为永清井水温的多次异常变化不是受干扰影响；通过对水温的异常变化与地震的对应关系的分析，认为永清井水温异常可能与3次地震有关。

| Abstract: | It is a primary task to distinguish whether the groundwater is affected by shallow material recharge or deep medium activity for the research of subsurface fluid. In this paper, the data of water chemical composition and hydrogen and oxygen stable isotope were obtained by collecting and testing several samples from Yongqing well and its surrounding areas. Through the comparison of groundwater sample data, water chemical composition, stable isotopes of hydrogen and oxygen and precipitation line, water temperature and water level data analysis, it is concluded that the repeated abnormal changes of water temperature in Yongqing well are not interference effects. According to the corresponding relationship between the abnormal change of water temperature and earthquake, it is founded that the abnormal water temperature in Yongqing well may be related to three earthquakes. |
