摘　　要：结合天津地区的地热地质条件,从影响地热可持续利用的因素考虑,指出了天津地热开发对水环境、地面沉降和地震活动产生的影响。指出尾水排入指定的公共污水管道可以解决环境污染,采取回灌的措施来防止地面沉降,利用井水汞异常来推断和预测地震的方法,减少和降低各种地质灾害的发生。使地热水资源能够合理开采,充分利用。Combined with the geothermal geological conditions in Tianjin Area and considering the impact factors of geothermal sustainable utilization,the paper presents the effects of the geothermal development in Tianjin Area on water environment, the ground subsidence and the seismic activity. It is pointed out that the tailing water is dispersed into the public sewage conduit can solve the environmental pollution, that the water recharge measure taken can prevent land subsidence and well mercury anomaly used can infer and predict earthquakes. Those measures we take can reduce the occurrences of geological disasters and make a rational exploitation and full use of the water resources.
