Urban form plays a critical role in enhancing urban climate resilience amidst the challenges of escalating global change and recurrent high-temperature heatwaves. Therefore, it is crucial to study correlation between spatial factors land surface temperature (LST). This utilized Landsat 8 remote sensing data estimate LST. Random forest nonlinear analysis was employed investigate interaction heat island (UHI) six morphological factors: building density (BD), floor area ratio (FAR), height (BH), fractional vegetation coverage (FVC), sky view factor (SVF), impervious fraction (ISF), within framework local zones (LCZs). Key findings revealed that Xi’an exhibited significant effect, with over 10% experiencing temperatures exceeding 40 °C. Notably, average LST building-class LCZs (1-6) 3.5 °C higher than cover-class (A-C). Specifically, compact (1-3) had an 3.02 open (4-6). FVC contributed most variation LST, while FAR least. ISF BD were found have positive impact on BH negative influence. Moreover, SVF observed positively influence classes (LCZ2-3) low-rise class (LCZ6). In mid-rise (LCZ5), showed U-shaped relationship. There inverted relationship inflection point occurring at 1.5. The results beneficial illustrating complex relationships its driving factors. study’s highlight effectiveness utilizing LCZ as detailed approach explore morphology islands. Recommendations for include strategies such increasing coverage, regulating heights, organizing buildings “L” or “I” shape, adopting “O” “C” configuration aid planners developing sustainable environments.

With rapid worldwide urbanization, the urban heat island (UHI) effect is becoming more and serious. The UHI intense in industrial areas. Green roofs are an effective way to mitigate UHIs high-density cities, which calls for thorough examination. This study explored associations between block characteristics thermal environment areas based on widely accepted Local Climate Zone (LCZ) scheme. pedestrian air temperature comparisons before after virtual green roof installations presented cooling effects of roofs. Thirty-six typical blocks were involved simulations conducted utilizing ENVI-met. results showed that (1) LCZ4 significantly lower than those LCZ2 LCZ6, but no significant differences identified other pairs LCZ types; (2) differs among LCZs, associated with sky view factor (SVF), average building area (ABA) shape index (ABSI); (3) areas, additional functional parameters building-volume indices should be included better address physical characteristics, environment, blocks. could improve validity classification may provide direct implications planning.

Longwave radiation is a crucial factor affecting human thermal comfort and stress, especially in outdoor spaces summer, owing to the vast effect of longwave emitted from high-heated asphalt roads, building walls, automobiles. Although controlling environment improve summer crucial, prediction frequently conducted only at assessment stage final proposal because high computational cost calculations unsteady heat balance analysis considering multiple reflections. This significant constraint for design urban architectural environments. A previous study proposed method rapidly estimate based on point-by-point with intensity distributions sources. To use this method, 3D models geographical objects areas, such as buildings trees, must be accurately generated, these should have information each direction object. However, no specific examples model distribution been presented. In study, modeling areas drones photogrammetric techniques was utilized. Moreover, small-scale generated. produced building.
