Current Situation and Prospect of Comprehensive Development of Underground Space in Metro Area

Nowadays, the shortage of available urban land and the booming construction of urban subways drive the rapid development of Underground Space in the Metro Area (USIMA), which has become an essential part of the comprehensive development and has significant research implications. In this paper, 73 high-standard articles were selected through the retrieval of Chinese and international literature related to USIMA, and ten topics with more attention were summarized from the macro, medium, and micro scales. The urban master planning level involves the related research of development models, development scale, and development planning guidelines. The detailed planning level involves the related research of spatial vitality, spatial layout, integrated aboveground and underground space design, and regulatory plan. Then, the level of architectural design involves the related research of spatial structure form, spatial orientation, and environment creation. Simultaneously, standard research methodologies are presented, such as case analysis, semantic differential, post-occupancy evaluation, regression analysis, and simulation. Based on this, this study presents feasible research topics and technique innovation, which has a significant reference value for the future full development and utilization of metro area underground space.
