Spatial gradients of urban land density and nighttime light intensity in 30 global megacities

M. Zheng, W. Huang, et al.

This study explores the intriguing relationship between urban land density and nighttime light intensity across 30 global megacities. Conducted by Muchen Zheng, Wenli Huang, Gang Xu, Xi Li, and Limin Jiao, it reveals how socioeconomic elements cluster quite differently within urban areas. A must-listen for those concerned with sustainable urban development!

Abstract

This study investigates the spatial gradients of urban land density (ULD) and nighttime light intensity (NLI) in 30 global megacities. Using the inverse-S function, it finds that both ULD and NLI decrease slowly near city centers, then decline rapidly in suburban areas, and finally decrease slowly again. NLI decreases faster than ULD, indicating a more pronounced spatial agglomeration of socioeconomic elements. This gap highlights the need for balanced development to avoid low-density urban sprawl and promote sustainable urban development.
