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.
