Quantitative Evaluation of the Potential of Underground Space Resources in Urban Central Areas Based on Multiple Factors: A Case Study of Xicheng District, Beijing

Abstract Compared with those of other areas, the conditions for the development and utilization of urban central areas are often more complex and diverse. Taking Xicheng District of Bejing as an example, this research sorts out and extracts the main factors influencing the development and utilization of underground space in urban central areas from the two aspects of supply and demand, explores the methods for the quantitative evaluation of the potential of underground space resources. Based on the detailed general survey and reconnaissance data on underground space by diversified data acquisition and analysis methods, the research comprehensively studies and analyzes all the factors influencing the underground space resources in Xicheng District and by establishing the classification indexes and the quantitative evaluation model, it develops the quantitative evaluation of the potential of underground space resources development and utilization based on the land units, which provides certain reference for the underground space planning in urban central areas and for the scientific and reasonable utilization of underground space resources.
