本文对太原南部地区(包括南郊、清徐、榆次)的井水温度测量值按井深绘制了温度等值线。同时对井水温度的分布规律进行了分析,发现两个水温较高带,这两条水温较高带与断裂构造、中小地震活动有很好的一致性。认为中部水温较高带,小店—王答一带可能存在着一条北东向活动断层,而且是本区近代活动最强烈的一条断层。 In this paper, the temperature contour of the well water temperature in the southern part of Taiyuan (including the southern suburbs, Qingxu and Yuci) is plotted according to well depth. At the same time, the distribution of well water temperature has been analyzed. It is found that the two water temperature zones are higher, and the higher one of these two water temperature zones is in good agreement with the fault structure and medium-small earthquake activity. It is believed that there may be a north-easterly active fault in the vicinity of the Wangdi-Aid area in the middle of the high temperature zone of the central China, and it is also the most intense fault of modern activities in this area.
