Abstract: Taking Suzhou city as the research background to explain the hydrologic geological conditions of the region's shallow geothermal energy resources, analysis of the groundwater source heat pump system applications may impact on the groundwater environment, which shows that Section Ⅱ is the ideal aquifer exploitation confined aquifer for groundwater source heat pump application in this region. On these bases, establish standards of suitability division by the theory of Analytic Hierarchy Process and Comprehensive Index, Suzhou city shallow groundwater source heat pump system application is divided into suitable area, the general suitable area and unsuitable area.This article provide an important basis on shallow groundwater source heat pump system and the development of rational exploitation of groundwater and other environmental protection measures in Suzhou city.
