摘　　要：通过对西安地区地热井水位、地面沉降和地裂缝活动、地震活动等资料的分析得到:西安市区地面沉降和地裂缝活动与地下热水开采有一定的联系;西安地区地下热水的开采与西安及邻区的地震活动明显相关,造成西安及邻区的地震活动性显著增强,在空间分布上表现为地震由西安城郊向邻近地区的转移。Based on the data analyses of the water level of hot water well, the ground subsidence and the activity of ground fissures in Xi＇an area,and seismic activity in Xi＇an and its neighboring area,the results show that the ground subsidence and the activity of ground fissures have some relationship with the geothermal water exploitation; the geothermal water exploitation in Xi＇an is obviously related to the seismic activity in Xi＇an and its neighboring area,and it intensifies the seismic activity in Xi＇an and its neighboring area,the distribution of earthquake epicenters migrates from the city of Xi＇an to its adjacent areas.

关 键 词：地热水开采 地面沉降 地裂缝 地震活动性
