Characterization of Multiple Resource Endowment in Urban Underground: A Case Study of Danyang City

Urban areas often contain interconnected underground resources, such as underground space, groundwater, shallow geothermal energy, and geological materials. Current evaluations of geological resources tend to focus on individual resources, neglecting a comprehensive assessment from a holistic perspective. This limitation has led to conflicts in resource development, compromised resource potential, and missed opportunities for synergistic resource utilization. In this study, the geologic body of Danyang City, where a comprehensive geologic survey has been conducted at a depth of 30m below the surface, is taken as the research object. Based on the division of regional geological units, the study assesses the endowment level of individual resources and proposes a “zonation radar chart” method to depict the comprehensive resource endowment of geological formations. Additionally, the study explores the application of this method in urban development planning, highlighting its significance in facilitating sustainable resource management and maximizing resource development opportunities.
