Rapid urbanisation and climate change have intensified land surface temperature (LST) and heat-related risks across large urban regions. However, existing research has mainly focused on single land-cover types or linear associations, offering limited insight into how multidimensional spatial morphology regulates LST under complex surface conditions. Focusing on the Chengdu–Chongqing region, this study integrated land use/land cover, building density (BD) and height, canopy height and ECOSTRESS LST data to examine the spatial heterogeneity and drivers of summer day and night LST across local climate zone (LCZ) types. Morphological spatial pattern analysis was used to characterise the 2D morphology of urban built-up space, urban green space and rangeland (RGL), whilst a CatBoost-SHAP framework was employed to quantify the importance, threshold responses and interactions of 2D and 3D morphological factors. Results show the following: (1) Regional cooling should prioritise dominant LCZ types rather than isolated hotspots, with LCZ 6 as the primary target and LCZ 5 as a secondary priority. (2) In built LCZ 5 and 6, cooling is more sensitive to 3D morphology, with canopy height showing stable cooling effects, whilst built-up coverage and BD intensify warming. (3) In natural LCZ types, cooling is governed more by 2D RGL structure, especially its coverage, core and branch. (4) Day mitigation relies more on taller canopies and restrained built-up expansion, whereas night cooling depends more on larger RGL patches and stronger RGL cores. These findings provide a robust basis for LCZ-based, spatially differentiated heat mitigation in regions characterised by complex surface conditions.
