摘　　要：根据西影井热水水位的观测资料,分析了区域地震活动与西安地区地下热水活动的相关性,结果表明西安地区地下热水活动与区域地震活动明显相关;西安地区地下热水活动与西安及邻区的地震活动最为密切,表明它们均受长安-临潼活动断裂的控制,西安市抽取地下热水的影响范围主要局限于西安及邻区,即临潼-长安活动断裂的展布区。Based on the geothermal water level data of Xiying well and the earthquake data recorded by the seismic network of Shaanxi Province, the correlation between the activity of geothermal water and regional seismic activity in Xiran area is studied. The results show that the activity of geothermal water in Xi＇an area is obviously related to the regional seismic activity, and has the closest relation with the seismic activity in Xiran and its neighboring area, indicating that they are both controlled by Changtan-Lintong fault. Thus the affected area of the geothermal water exploitation in Xi＇an city is mainly limited within Xiran and its neighboring area, where Chang＇an-Lintong fault is distributed.
