Abstract Context Land use/cover change (LUCC) can directly and indirectly affect surface urban heat island intensity (SUHII) the effects need to be decomposed. Objectives To perform long-term trend analyses of contribution indexes (CIs) land use types environment in cities deconstruct direct indirect LUCC on SUHII within geographical regions. Methods Mann–Kendall test Sen’s slope were used examine trends CIs 365 during summer 2005–2019. Structural equation models established quantify types’ six regions China. Results First, 78.08% 73.70% Chinese increased daytime nighttime, respectively. Second, CI built-up significantly across more than half all Third, not exerted both SUHII. At daytime, cropland (direct) was dominant factor East China (1.386), South-central (− 0.637), Northwest 0.399) water bodies (both indirect) (0.506) Northeast (0.697) while determined North (0.476). Conclusions Separation had practical implications for optimize structures functions ecosystems take regionally based actions improving environment.

Nonlinear effects of urban multidimensional characteristics on daytime and nighttime land surface temperature in highly urbanized regions: A case study in Beijing, China

It is crucial to clarify the nonlinear effects of urban multidimensional characteristics on land surface temperature (LST). However, combined consideration green space (UGS), water bodies, buildings, and socio-economic factors limited. And diurnal differences in their thermal have been less considered. In this study, central Beijing was taken as study area. Local climate zones (LCZ) were firstly applied reveal spatiotemporal heterogeneity LST. Then, interpretable machine learning methods utilized quantitatively characteristics, i.e., UGS, building landscape features, features. The results indicated that built type LCZs a higher average LST compared natural LCZs. simultaneously influenced by buildings' density height characteristics. Daytime mainly affected proportions trees, while nighttime more key exhibit Whether during day or night, impact coverage greater than height, consistently exhibiting warming effect. While, body edge both exhibited reversal trend between night. Our also emphasized importance trees UGS provided recommendations for planning based sensitivity contribution considerations. These findings can help regulate promote sustainable development.

Temporal and spatial variations of urban surface temperature and correlation study of influencing factors

Urban overheating significantly affects thermal comfort and livability, making it essential to understand the relationship between urban form land surface temperature (LST). While horizontal dimensions of have been widely studied, vertical structures their impact on LST remain underexplored. This study investigates influence three-dimensional characteristics LST, using ECOSTRESS sensor data four machine learning models. Six morphology variables—building density (BD), mean building height (MH), volume (BVD), gross floor area (GFA), ratio (FAR), sky view factor (SVF)—are analyzed across different seasons times day. The results reveal that MH, BD, FAR are season-stable factors, with higher MH correlated lower ((e.g., an observed reduction approximately 3 °C in spring), while BD is associated (e.g., increase about 3.5 autumn). In contrast, BVD, GFA, SVF season-varying factors variable impacts depending time year. Higher BVD generally elevated GFA linked LST. These associations reflect absolute changes measured directly from data. findings offer valuable insights into complex interactions helping inform strategies for heat mitigation sustainable planning.
