Abstract
The study examines the changes in the local climate zone (LCZ) and the surface urban heat island intensity (SUHII) of Chang-zhu-tan main urban area from 2000 to 2017. Firstly, it analyzed the land cover changes in Chang-zhu-tan from 2000 to 2017 by exploring the distribution of LCZ types. Secondly, mean LST of LCZs were obtained to evaluate the SUHII layout. Thirdly, it deals with critical LCZs in SUHII and seeks to understand how to approach mitigation strategies for Chang-zhu-tan. The results showed that, firstly, the land cover LCZs of the suburban areas adjacent to the three cities were most likely to be replaced with built-up LCZs from 2000 to 2017. Secondly, SUHII varies among different LCZs. LCZ-10 contributed to the strongest SUHII (around 5–6 °C) in 2000 and 2005, while LCZ-5 had the highest SUHII (around 6–7 °C) from 2011 to 2017, which tended to occur around the urban centers. By contrast, LCZ-A-D and LCZ-G contribute to cool areas (around 0–2 °C) throughout the study period.The findings help better understand the relationship between SUHII and LCZs and provide a more scientific basis for urban environmental planning.
