摘　　要：利用区域水文地质资料、水温梯度测试结果、区域地下水开采和降水等数据,分析了影响内蒙古通辽地震观测井水位和温度多年与年际变化的因素。在此基础上,构建了水动力地质模型,探讨了该井水位和水温准同步变化的机理。结果表明,区域地下水开采和降雨是影响该井水位和温度准同步变化的主要因素,冷水渗透理论可以很好地解释该井水位和水温的准同步变化。Using regional hydrogeological data,water temperature gradient test results,regional groundwater exploitation data,and precipitation data,the factors affecting the multi-year and interannual changes in water level and temperature in the Tongliao earth-quake observation well in Inner Mongolia were analyzed.On this basis,a hydrodynamic geological model was constructed to explore the mechanism of quasi synchronous changes in water level and temperature in the well.The results indicate that regional groundwater extraction and rainfall are the main influencing factors for the quasi synchronous changes of water level and temperature in the well,and the cold water infiltration theory can well explain these quasi synchronous changes.
