【Abstract】 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.更多还原
