Research on Functional Restructuring of Waterfront Spaces Driven by the Low-Altitude Economy: A Case Study of the Nanjing “Jiangyida” Low-Altitude Flight Base

With the low-altitude economy being elevated to a national strategic emerging industry development plan, the “two-dimensional plane” urban space will transform into a “three-dimensional space.” This article uses the Nanjing “Jiangyida” low-altitude flight base as a case study, demonstrating how low-altitude infrastructure promotes the functional upgrading of waterfront spaces. This demonstrates that the low-altitude economy can bring about three-dimensional development and functional enhancement of waterfront spaces. However, it also presents challenges such as technological and institutional friction and social acceptance. The proposed “double-helix reconstruction model of low-altitude waterfront spaces” reveals the coupling relationship between technological application and institutional adaptation, providing theoretical support and practical reference for the development of the low-altitude economy in waterfront cities.
