摘　　要：在大量的野外调查与试验基础上,对宿迁城市规划区浅层地热能开发利用进行适宜性评价,估算了浅层地热能热容量及可利用资源量,讨论了开发利用的经济效益和环境效益,提出了科学有序开发利用浅层地热能资源的建议。实测100 m以浅岩土体初始温度变化较小,区域上表现为南北低中间高的特征,恒温带平均深度为16 m,平均温度16.6℃。规划区适宜选择竖直地埋管地源热泵系统开发浅层地热能,其适宜区面积占64.2%,较适宜区占22.8%。浅层地热能热容量约4.62×10^14kJ/℃,可利用资源量达1.18×10^14kJ/a。据估算,浅层地热能开发可为规划区节省标准煤5.16×10^6 t/a,减少CO2排放约1.23×10^7 t/a,并减轻大气污染。Based on a large number of field investigations and experiments,the suitability evaluation of development and utilization of shallow geothermal energy in urban planning area of Suqian was carried out.The shallow geothermal capacity and available resources were estimated.Moreover,the economic and environmental benefits from development and utilization were discussed.We proposed scientific and orderly development and utilization of shallow geothermal energy resources finally.Measured data at 100 meters shows that the initial temperature change of the shallow rock and soil is small,and the distribution of regional temperature has the characteristics of low values in the north and south,while high values appear in the middle of urban planning area of Suqian.The average depth of the constant temperature layer is 16m and the average temperature is 16.6°C.The urban planning area of Suqian is suitable to choose a vertical buried pipe ground-source heat pump system to develop shallow geothermal energy.The area that best suits for the ground-source heat pump system accounts for 64.2%and the area that better suits accounts for 22.8%for the ground-source heat pump system.The total shallow geothermal capacity and available resource are 4.62×10^14 kJ/℃and 1.18×10^14 kJ/a respectively.It’s estimated that about 5.16×10^7 t/a standard coal will be saved by exploring and utilizing the shallow geothermal energy in the urban planning area of Suqian.Besides,emission of CO2(about 1.23×10^7 t/a)and air pollutants will also be reduced.
