摘　　要：天津市浅层地温赋存特征与第四系息息相关,第四系地质结构为粘土、粉质粘土、粉砂、细砂、粗砂互层,岩土体热导率:1.23-1.58W/(m·℃),比热容1898.52-2201.70W/(m·℃),地下水涌水量为100-3000(m^3/d),导水系数50-300(m^2/d),地下水回灌量30-80m^3/h,单井回灌量是出水量的30%-50%,回灌量大部分在50m^3/h以下,地层排热量32.32-126.1(w/m),吸热量17.73-66.8(w/m)。针对该区浅层地温能利用方式(地下水源热泵、地埋管地源热泵)计算了适宜区与较适宜区的浅层地温能储量和换热功率,阐述了由此资源潜力带来的经济和社会价值,并提出天津市浅层地温能优化开发利用方向及其对策。The occurrence characteristics of shallow geothermal energy are closely related to Quaternary system in Tianjin. The geological structure of Quaternary is interbedded strata of clay, silty clay, silt,fine sand and coarse sand. The thermal conductivity of rock and soil is 1.23-1.58W/（m·℃）. The specific heat capacity is 1898.52-2201.70W/ （m·℃）.The water inflow yield of the groundwater is 100-3000 （m3/d）.The transmissivity is 50-300 （m2/d） .The reinjection of groundwater is 30-80m3/h. The reinjection quantity of single well is 30-50% of the inflow yield. Most of the reinjection quantities are below 50m3/h. The heat exhaustion of formation is 32.32-126.1. The heat absorption is 17.73-66.8 （w/ m） .On the analysis of shallow geothermal energy utilization modes （groundwater source heat pump and buried pipe ground-source heat pump） , we calculated the reserves and the exchange power of the shallow geothermal in the suitable area and less suitable area for utilization and expound the resource potential of the economic and social value. At last, we provide an optimum proposal and response for the development and utilization of the shallow geothermal energy resources.
