Summary

Rapid urbanization intensifies urban heat island effects, creating significant challenges for sustainable urban development and environmental comfort. Vegetation plays a key role in mitigating urban heat through its capacity to regulate surface temperatures and improve microclimatic conditions.

This research examines the relationship between urban vegetation and land surface temperature (LST) using a geospatial approach based on satellite remote sensing. The results reveal a clear inverse relationship between vegetation density and surface temperature: highly vegetated areas show lower temperatures, while densely built and mineralized zones correspond to higher thermal intensities.

The study highlights the importance of integrating urban vegetation into planning and architectural strategies. Green infrastructure can play a crucial role in reducing thermal stress and improving environmental quality. These findings support climate-responsive urban design and provide useful insights for sustainable and resilient urban development.
