摘　　要：研究深层含水系统水位、水温动态 ,目前多以变化形态的描述和年动态特征的分析为主。本文根据水位、水温的变化关系 ,研究了两者线性相关系数 r值的稳定性和回归系数 b值随时间的变化 ,发现地震活动平静时间段的 r值和 b值相对稳定 ,而在地震活动频繁、强度较高时间段的 r值和 b值变化较大。文章对 1 989年 1 0月 1 9日大同 6 .1级地震和 1 995年以来地震活动性及 1 998年 1月 1 0日张北 6 .2级地震前后 r值和 b值的变化进行了讨论 ,显示了比单一分析水位或水温动态能够获得更多的信息。从对深层地下水动态与水温关系的分析认为 ,水位动态是深层含水系统热动平衡状态的反应 。Study on deep aquifer's water level and water temperature dynamics is mainly by the describing of the morphologic variation and the analysis to annually dynamic character at present.Based on the relation between water level and temperature,the stability of the linear correlation coefficient r and the variation of regression coefficient b with time are studied.We find the r and b values are stable during the period that earthquake activity is quiet,but vary greatly when earthquake is active.The variations of r and b value before and after Datong Ms6.1 earthquake (Oct.19,1989) and Zhangbei Ms6.2 earthquake (Jan.10,1998) are discussed.The results show we can get more information through comparison than just to discuss them respectively.From the analysis to the relation of underground water level with water temperature we can see that the water level's variation is the response of the aquifer system's thermal balance.Thus to study the underground water level's dynamics we must study the temperature's variation simultaneously.
