The Role of Urban Green Infrastructure in Improving Thermal Environment and Resident Health: A Case Study in Changsha, China

Urban Farm DB summary

This study investigated the cooling effects of five urban green spaces in Changsha, China, using Landsat 9 remote sensing images from 2022-2024. Land surface temperatures were calculated for Yuelu Mountain, Martyrs' Park, Yuehu Park, Xiaoyuan Park, and a community garden. Large green spaces like Yuelu Mountain and Martyrs' Park showed the best cooling effects, lowering surrounding surface temperatures by up to 7.3°C compared to built-up areas. The findings indicate that more vegetation correlates with lower land surface temperatures.
