How Urban Morphology Relates to the Urban Heat Island Effect: A Multi-Indicator Study

Sustainability, Год журнала: 2023, Номер 15(14), С. 10787 - 10787

Urban morphology quantitatively expresses a city’s spatial structure, internal relationships, and physical form. It has advantages for predicting urban growth analyzing the current state of cities in literature. A comprehensive study on complex relationships between heat island intensity (UHII) is great importance mitigating (UHI) effect megacities. This models morphological indicators fine resolution based three aspects: building morphology, ecological infrastructure, human activities. The model accurately captures UHII by employing definition UHI effects. relationship was further examined using extreme gradient boosting (XGBoost) Shapley additive explanations (SHAP). By taking central Beijing, China as area, major findings include following: (1) Significant daytime effects were observed within research particularly during summer months, when it appears to be most severe. More than 90% region experiences varying degrees (2) significantly correlated with both 2D 3D indicators. Low sky view factor (SVF) high SVF tend mitigate UHI, whereas moderate tends aggravate UHI. (3) In densely populated areas, tall trees may more effective other forms vegetation at Based aforementioned findings, this article suggests that optimization should focus seasonality, specificity, indicator specificity megacities design planning aimed

Urban form has been confirmed to be a contributor the Heat Island (UHI) effect in metropolitan areas, but few studies have focused relationship fast-growing small cities through LCZs approach. How Local Climate Zones (LCZs) distributes and whether correlations between UHI intensity (UHII) urban differ cites large remain studied. This study mapped analyzed UHII Yangling, city China using GIS-based method. The results showed: (1) 37 % of area contained "High" "Very High" UHII, mainly areas with high building density expansive impervious surfaces. maximum Yangling was below 40 °C, which lower than that many cities. In addition, scattered formed small-scale cluster different from where large-scale agglomeration areas. (2) Unlike previous findings megacities, open Low-rise (LCZ6) most prevalent LCZ Yangling. (3) build-up (2.01 °C) significantly higher those natural types (-0.61 °C), compact (LCZ1-3) (LCZ4-6). (4) Natural factors were negatively correlated whereas positively on greater factors. These will help climate researchers planners better understand apply this knowledge build more comfortable thermal environment.
