Abstract: The resource monitoring network of shallow geothermal energy based on the investigation and related research work of shallow geothermal energy in Chongqing in recent years and combined with the constructed project of the shallow geothermal in development and utilization was established to conduct dynamic monitoring of ground-source heat pump system.The ground temperature was cyclical change along with the operation of the system，and the change range of the ground temperature for the operation hole was significantly higher than that of drilling holes along the edges，through gathering temperature data of typical ground-source heat pump project from March 28th, 2011 to October 28th, 2014 and the comparative analysis of ground temperature variation before and after the operation of system.The average temperature change curve of the recovery period after the operation of the system was drawn，and it was discovered that there was upward trend in the average temperature of soil and slight heat accumulation.At present，the system is running in a good condition and the ground temperature does not have a significant impact on the system.

Key words: shallow geothermal energy, monitoring network, ground-source heat pump, geothermal field

摘要： 基于近几年对重庆地区浅层地温能的调查研究及相关科研工作，结合已施工的浅层地温能开发利用项目，建立浅层地温能资源监测网，对地源热泵 系统进行动态监测。采集典型地源热泵工程2011年3月28日~2014年10月28日的地温数据，通过对比分析系统运行前后地温变化，认为地温会随着系统的运 行产生周期性的变化，运行孔的地温变化幅度会明显高于周围钻孔。绘制系统运行后恢复期的平均温度变化曲线，发现土壤平均温度呈上升趋势，产生轻 微热堆积情况，目前该系统运行状况良好，地温变化未对系统产生重大影响。
