摘　　要：通过案例计算,分别对地下水源热泵采用定流量和定压差2种运行方式对含水层参数变化特性的影响进行研究.研究结果表明,与地下水源热泵采用定流量运行方式相比,采用定压差运行方式时含水层孔隙率和渗透系数平均增大率分别为0.45%和2.07%,采用定压差运行方式对含水层参数变化特性的影响程度大于定流量运行方式.对于完整井,增大取水井井径和含水层厚度会使2种运行方式对含水层参数变化特性的影响减弱.The influence on the variation characteristics of aquifer parameters, induced by groundwater source heat pump （GWSHP） operation under constant flow and constant pressure difference, was theoretically analyzed by ease study. The present study, compared with the constant flow operation, indicates that the porosity and hydraulic conductivity increase by 0.45 % and 2.07 0% respectively under constant pressure difference operation. The influence on the variation characteristics of aquifer parameters, under constant pressure difference operation, is greater than constant flow operation. For the full penetrating well, the influence on the variation characteristics of aquifer parameters decreases gradually with the increase of the borehole diameter and aquifer thickness under different operation modes.
