Despite increasing attention to rising land surface temperatures (LSTs) and other climate changes caused by urbanization, few studies have considered the characteristics of LST or thermal comfort of human settlements from a regional perspective. Therefore, to explore the regional characteristics of LST and thermal comfort in Zhengzhou, China, we calculated the predicted mean vote (PMV) based on local climate zones (LCZs) using ENVI-met and studied correlations between LSTs and vegetation-type LCZs. The total land area under human settlements in Zhengzhou is 316.26 km², 52.72% of which is accounted by LCZs of buildings. The LSTs of built-up areas in this region were significantly higher than those of natural surfaces, with the highest and lowest LSTs of 37.98 °C (in LCZ3; compact low-rise buildings) and 32.46 °C (in LCZG; water areas), respectively. Under the same conditions, the PMV value was …
