摘要
地源热泵是上海开发利用浅层地温能的主要形式。通过对上海地区不同地点、不同埋深范围内第四纪地层地温实测数据,分析了本地区浅层岩土温度场分布的一般规律,并与历史数据比较。40余年来,上海地区第一承压含水层的平均地温有小幅升高,而第二承压含水层则有小幅下降。影响浅层地温场分布的主要因素有太阳辐射的周期变化、城市热岛效应、地表植被、地下水径流、人工回灌等。本文可为本地区地埋管地源热泵系统的勘察设计提供参考。
Ground source heat pumps （GSHPs） represent the major mode of utilization of shallow geothermal energy in Shanghai. Using temperature data measured at various sites and at different depths for Quaternary strata in the Shanghai area, this paper analyses the characteristics of the shallow-rock and soil temperature field distribution and compares it with historical data. Over a period of 40 years, the average ground temperature in the first confined aquifer has risen slightly but that of the second confined aquifer has fallen slightly. The main factors affecting the shallow geothermal field temperature distribution include periodic changes in solar radiation, the urban heat island effect, the type and distribution of vegetation, groundwater runoff, and artificial recharge. The research results will provide a basis for the prospective design of GSHP systems with buried pipes in the Shanghai area.
