With fast population growth and urban densification in some cities, the urban space in the high-density environment has a tendency towards “ verticalization.” The complexity of verticalized urban space reflected not only in the physical perspective, but also expressed by how people use these urban spaces. This research tries to offer a three-dimensional point of view to describe the geographical morphology and further more to analyzing the urban spatial structure and human behavior in the so-called “Vertical City” by both qualitative and quantitative methods.
