Description
With the rapid development of drone technology, urban low-altitude airspace planning has become an indispensable part of future urban planning. Based on the theory of re-collage city, this paper explores the collaborative development strategies for urban low-altitude airspace, ground space, and underground space, aiming to protect historical sites, promote ecological conservation, ensure privacy and safety, and revitalize physical commerce. The re-collage city theory emphasizes the diversity, historicity, and complexity of urban space, advocating for the harmonious integration of fragments from different times, cultures, and functions in urban design. In the planning of urban low-altitude airspace, this theory requires us to comprehensively consider the integration of historical ecological protection and modern development, the fusion of ground transportation and aerial routes, and the coexistence of promoting social interaction and protecting privacy. Urban low-altitude airspace planning should be regarded as a new dimension of urban planning, forming a three-dimensional spatial structure of the city together with ground buildings and underground facilities. In terms of planning strategies, the first step is to clearly delineate the layered division of low-altitude airspace to ensure effective connection with the existing urban planning system. By constructing refined airspace structures, such as tubular airspace and layered airspace, traffic efficiency and safety can be enhanced. At the same time, based on the characteristics of drone technology and urban development needs, the airspace capacity should be scientifically assessed, and resource allocation should be optimized according to the spatial location of historical and cultural heritage sites and physical commercial functions. Furthermore, ecological protection and privacy safety must be fully considered in the planning process. By reasonably planning low-altitude airspace routes, damage to the ecological environment and impacts on biological habitats can be avoided. Meanwhile, privacy protection measures should be strengthened to ensure that drone flights do not infringe on residents' privacy. It is worth noting that with the development of low-altitude airspace, buildings will no longer be limited to having entrances only at the ground level. Instead, entrances at the top or intermediate levels will be encouraged to achieve seamless connections between the air and the ground. This requires us to pay attention to the integrated design of roof or intermediate-level spaces in urban low-altitude airspace, such as aerial corridors and rooftop terminals, forming a three-dimensional urban transportation and social interaction network. The urban low-altitude airspace planning strategy based on the re-collage city theory aims to promote the three-dimensional development of urban space, achieve harmonious coexistence between history and modernity, realize a win-win situation between ecological protection and economic development, and balance residents' privacy with commercial revitalization. In the future, research and practice in this field will provide strong support for building smarter, greener, and more livable urban spaces.
