苏州市区多种地下地质资源协同开发利用研究

Study on the collaborative development and utilization of multiple underground geological resources in Suzhou urban area

地下空间、地下水、浅层地热能和地质材料是重要的地下地质资源,协同开发利用是大势所趋。苏州既是历史文化名城又是现代国际化大都市,城市发展至今对地下地质资源的需求相当迫切。通过对苏州各类地下地质资源的的识别分析,表明其具备分别开发地下空间、地下水、浅层地热能和地质材料资源的能力。若多种资源协同开发,平面上开发利用条件较好,竖向尺度地下浅层到次深层适宜地下空间和地质材料的协同开发,而深层适宜以浅层地热能为主的协同开发。结合苏州国土空间发展格局和地下资源的优势分布特征,城镇空间建议采取“地下空间+浅层地热能”的协同利用模式;农业空间建议采取以“浅层地热能”为主的协同利用模式;生态空间予以生态环境保护。

Underground space,underground water,shallow geothermal energy and geological materials are important underground geological resources,and collaborative development and utilization is the general trend.Suzhou is both a famous historical and cultural city and a modern international metropolis.The demand for underground geological resources is quite urgent since the development of the city.Through the identification and analysis of multiple underground geological resources,it is found that Suzhou has the ability to develop underground space,groundwater,shallow geothermal energy and geological material resources respectively.If multiple resources are jointly developed,the development and utilization conditions on the plane are better.The vertical scale from shallow underground to sub-deep underground is more suitable for the collaborative development of underground space and geological materials,while the deep layer is more suitable for the collaborative development of shallow geothermal energy.Combined with the development pattern of Suzhou’s land space and the advantageous distribution characteristics of underground resources,it is suggested to adopt the"underground space+shallow geothermal energy"coordinated utilization mode for urban space;It is suggested to adopt the cooperative utilization mode of shallow geothermal energy in agricultural space;Ecological space is based on ecological environment protection.
