Urban Underground Space

Urban underground space (UUS) refers to the spatial resources developed and utilized underground in cities. With the continuous advancement of urbanization, land area within cities has become scarce, prompting the construction of many facilities underground. The utilization of UUS promotes low-carbon, sustainable urban development by optimizing urban spatial structures, improving urban infrastructure, and fostering green cities. For instance, the construction of large facilities like parking garages and shopping malls underground can release expansive areas in urban centers. Thus, moving structures underground conserves aboveground land resources and provides space for blue-green urban spaces.
