摘要: 浅层地温能属于清洁、安全、可再生的地热资源，是国家重点支持开发利用的能源方向.徐州城市规划区总面积3157km2，主城区面积641km2.通过调查规划区水文地质-工程地质钻探、热物性试验、施工钻孔热响应试验等工作手段，大致查明了规划区浅层地温能赋存的地质背景、形成条件、分布规律及地温场特征，进行浅层地温能开发利用适宜性分区，进而进行浅层地温能资源潜力评价及环境效益分析.根据评价分析结果，若徐州市城市规划区的浅层地温能资源全部开发利用，节能减排效益十分可观.Abstract: Shallow geotherm is a kind of clean, safe and renewable energy. The urban planning area of Xuzhou City, Jiangsu Province, covers a total area of 3157km2, including 641km2 of downtown area. Based on the hydrogeological and engineering geological drilling, thermal property test and thermal response test in the planning area, this paper recognizes the geological background, forming conditions, distribution and geothermal field characteristics, and divides the suitability zones for exploitation and utilization of shallow geothermal energy, then evaluates the resources potential and analyzes the environmental benefits. The results show that the energy saving and pollution reduction effect is considerable.
