摘　　要：地下水源热泵系统是利用浅层地温能的一种主要方式,而水文地质条件是决定应用地下水源热泵系统是否合理的主要因素之一,应用数值模拟的方法对地下水源热泵抽水井处地下水温度进行模拟,分析了含水层渗透率和孔隙度对地温场演化的影响。研究结果表明:在抽、灌量和生产井几何参数相同的条件下,含水层渗透率和有效孔隙度对地温场的演化影响并不显著。The groundwater source heat pump system is one main way of using shallow geothermal resources,but hydrogeological condition has a critical influence to the rationality of the groundwater source heat pump system.The paper simulates the temperature field of pumping well of the groundwater source heat pump system,analyzes the influence of permeability and porosity of aquifer to the change of the groundwater temperature.Results indicate that：in the condition that the geometric parameters of the volume of pumping water and recharging water,as well as the producing well,are the same,the influence of permeability and porosity of aquifer to the change of the groundwater temperature is not remarkable.
