The urban heat island effect refers to increased temperatures in highly developed urban areas and has negative impact for human activities and the social environment. This project aims to address this effect by integrating urban forests into the cityscape, while enhancing the living experience of residents. The project focuses on analyzing cool vegetation characteristics in existing areas and incorporating them into subsequent designs to utilize trees’ cooling capabilities, in order to combating the urban heat island effect and promoting city climate mitigation ability. Through analyzing the urban ground surface temperature and its relationship with trees, a positive correlation exists. The further design strategy considers tree types, leaf cooling rates, appropriate tree arrangements, and species selection, while addressing factors like shade coverage and adaptability to the urban environment. Except involves improving existing climate weak areas, this project also formulating a climate mitigation urban development strategy around the urban forest for the city future development. It’s important to note that the temperature discussed in this project refers specifically to urban surface temperature.
