摘　　要：北京市水源热泵的应用,宏观上未充分考虑地下水水源地的分布,微观上未注重应用场地的水文地质条件,地下水回灌率低造成了水资源浪费。本文针对北京平原区的水文地质条件,以浅层含水层导水系数、有效导水系数、地下水中的铁和总硬度为评价因子,以水源地保护区及补给区、地面沉降中心区为约束因子,利用叠加分析技术,将平原区分为适宜发展区、较适宜发展区、限制发展区和禁止发展区,为水源热泵的理性推广提供了技术参考。Application of the groundwater heat pumps in the plain of Beijing have neglected two problems.The first is some heat pumps were in protected area of groundwater sources,the second is that the site hydrogeological condition were not taken into consideration very well,which caused clog of return well and groundwater waste.The paper used surperpositon analysis to divide the suitable zone for groundwater heat pumps,which used transmissivity,effective transmissivity,iron and hardness as evaluation factor and protected area of groundwater sources and ground subsidence center area as restrictive factor.The four subzones were formed,which were four zones of suitable,less suitable,constrained and forbidden.
