| Abstract | Anthropogenic heat (AH), an essential urban heat source, is often overlooked or simplified in research on the multiple
temporal and spatial driving mechanisms of the urban heat island (UHI), and
case studies investigating the impacts of different AH connotations are scarce.
This study estimated the AH in seven typical Chinese cities based on a remote
sensing surface energy balance model (AHseb) and an energy consumption
inventory-machine learning model (AHinf). The intensity of the surface UHI was
extracted using land surface temperatures, and then the linear mixed-effects
model and geographic detectors were used to analyze the driving effect of AH on
the UHI. Despite the similar shapes of the spatial profile curves, the AH
derived from the two models differed in both temporal and spatial
characteristics, which was more typical in winter and in urban centers, and
AHinf had a more notable central spread feature than AHseb. The AH driving
effects on UHI were notably influenced by spatial and temporal heterogeneity,
particularly in regions with distinct background climates. However, after
controlling for the random effects of the background climate, AH still
exhibited a considerable enhancing effect on the UHI. AHseb outperformed AHinf
in terms of linear positive correlation and interpretation rate for UHI.
Meanwhile, interactions with other potential factors enhanced AH driving
effects. Consequently, UHI mitigation must be tailored to the local context by
integrating multiple drivers, and for the heating effects of AH, it is
necessary to develop specific mitigation measures by limiting the conversion of
AHinf to AHseb in addition to reducing the heat production. The findings offer
guidance for analyzing and optimizing urban thermal climates with a focus on AH
or energy consumption control. |
