Trees and their morphology can mitigate the urban heat island (UHI) effect, but impacts of tree species two-dimensional (2D) three-dimensional (3D) morphological characteristics on thermal environment residential spaces at building scale have not been effectively evaluated. This research extracted data trees in spatial range a 50 m radius sampling sites located subtropical humid city’s area based unmanned aerial vehicle (UAV) imagery field measurements. It included Ficus microcarpa L. f., Cinnamomum camphora (L.) J. Presl, Alstonia scholaris R. Br. as three typical evergreen six quantitative indicators trees, with number (N) serving fundamental indicator mean canopy width (MCW), height (MCH), (MTH), biomass (CV), (MCV) characteristic indicators. We analyzed impact above two parameters: Air temperature (AT) relative humidity (RH), by correlation analysis multiple linear regression analysis. Results showed that: (1) F. microcarpa, dominant local species, provided more than 65% volume within study (50 buffer zones), its contribution to cooling humidification effects was superior those C. A. scholaris. (2) The MTH CV are key factors influencing daytime AT RH, respectively, temporal fluctuation intensity during spring (May) daytime. (3) N show best effect (adjusted R2 = 0.731, p < 0.05) midday (13:00–14:00 p.m.), while 0.748, morning (9:00–10:00 a.m.) among species. 2D 3D describe variation microclimate small-scale spaces. work provides new insights into benefits brought growth features offers reference for areas planning management related selection, maintenance, improvement comfort inhabitants.

With the acceleration of urbanization, urban heat island (UHI) effect has become a major environmental challenge, severely affecting quality life residents and ecological environment. Quantitative analysis factors influencing intensity (UHII) is crucial for precise planning. Although extensive research investigated causes UHI effects their spatial variability, most studies focus on macro-scale analyses, overlooking heterogeneity thermal characteristics within local climate zones (LCZs) under rapid urbanization. To address this gap, study took central area Chengdu, constructing LCZ map using multisource remote sensing data. Moran’s Index was employed to analyze clustering across different LCZs. By Ordinary Least Squares (OLS) Geographically Weighted Regression (GWR) models, further explored these zones. The results showed that: (1) Chengdu’s built natural environments had comparable proportions, with scattered building zone comprising highest proportion at 22.12% in environment, low vegetation accounting 21.8% UHII values ranged from 10.2 °C −1.58 °C, based specific measurement conditions. Since varied meteorological conditions, time, seasons, selection rural reference points, represented dynamic during period were not constant. (2) morphology exhibited significant heterogeneity, global I index 0.734, indicating high degree correlation. value found impervious surfaces (0.776), while lowest floor ratio (0.176). (3) GWR model demonstrated greater explanatory power compared OLS model, fit 0.827. impact morphological significantly environments, substantial difference observed sky view factor, which standard deviation 13.639. findings provide recommendations planning, aiming mitigate enhance residents.
