Overview

Analysis reveals spatial correlation between urban green space and surface temperature in Changsha, suggesting mitigation strategies for heat islands.

Key Points

  • The analysis shows that increased urban green space significantly lowers surface temperature, mitigating the urban heat island effect.
  • Utilizing Landsat 8 imagery from 2013 to 2019, the study finds a high surface temperature in densely built-up areas along with stable negative correlations with vegetation.
  • By applying Pearson's correlation and cold hotspot analysis, the findings highlight the importance of strategic green space planning in urban areas.
  • The results suggest practical strategies to optimize green space allocation, benefiting urban planning and sustainability efforts.
