How Urban Characteristics Impact Surface Urban Heat Island in Subtropical High-Density Cities Based on Lczs: A Case Study of Macau

Опубликована: Янв. 1, 2024

Although numerous studies have explored the influence of urban spatial characteristics (USC) on surface heat island intensity (SUHII) from perspective local climate zone (LCZ), spatio-temporal heterogeneity within and between LCZs has not been demonstrated. In this study, a total 1540 grid units in Macau across 7 years were screened as research samples. USC, SUHII LCZ calculated derived multi-source data. GWR GTWR models applied to detect non-stationarity USC SUHII, Geodetector was used for ranking interpretation strength driving factors each class. Results show that 8 is highest. Besides, model had best fitting degree accounting thermal variations due form changes, regression performance generally different among classes, especially compact-types open-types. Furthermore, strategies related optimization finally proposed class based contribution factors. This study sheds new light "USC-SUHII-LCZ" linkage provides specific planning recommendations environment improvement, subtropical highdensity cities.

Under rapid urbanization, the urban heat island (UHI) effect is increasing, which poses a serious threat to human settlements. Changes in neighborhood land surface temperature (LST) reflect UHI at finer scale, with implications for thermal comfort of residents. Landsat images were used analyze distribution heat/cool (UNHI/UNCI) within fourth ring area Shenyang City. Three-dimensional buildings and functional zones (UFZs) combined explore relationships UNHI UNCI. Using boosted regression trees relative importance UFZs UNCI, results showed significant lowering on LST increased building height, may be due fact more architectural shadows generated by higher buildings. As size green space patches increased, cooling amplitude influence distance had an increasing trend. Industrial public service most UNHI, influences 30.46% 19.35%, respectively. In comparison, water contributed UNCI effect, 18.75% 11.95%, These will provide decision-makers crucial information mitigating problems through planning.
