昌黎井含水层系统的水位水温动态关系与地震活动

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，而在地城活动频敏，强度较高时间段为r值和b 值变化较大，文章对1989年10月19日大同6．1级地震和1995年以来地震活动性及1998年1月10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，研究水位动态必须同时研究地下水热动态。

Relation between water level and water temperature in the aquifer system of Changli well and seismicity

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.
