Multi-temporal remote sensing diagnosis of urban cooling networks: mechanisms and pathways of thermal degradation in Dongguan
Jing Qiu
IntroductionUnder the double pressure of climate change and rapid urbanization, the degradation of the urban thermal environment has become a major obstacle to regional sustainable development. As a manufacturing-leading metropolis, Dongguan has undergone a drastic land use transformation and ecological space compression since 2000, potentially undermining its urban cooling system.MethodsIn this study, multi-temporal Landsat imagery was used to characterize the spatiotemporal evolution of land s
