This study takes Chengdu City as an example to explore the improvement and optimization of urban thermal environment under the concept of park city.Firstly,the composition and formation of urban thermal environment are analyzed,and it is realized that factors such as human activities,building heat emissions,and lack of green spaces have significant impacts on the urban thermal environment in the process of urbanization,and the existing problems and deficiencies are pointed out.After fully understanding the relationship between land use and urban thermal environment,the study found that by rational planning of urban spatial structure,using rooftop photovoltaic panels combined with planting technology to increase rooftop greening,and adding urban parks to improve ground reflectivity and reduce heat generated by human activities,the urban heat island effect can be alleviated and the urban thermal environment can be improved.This study proposes a series of methods to improve the urban thermal environment and strategies for optimizing urban thermal environment design,which can provide important references for urban planning and construction.By optimizing the urban thermal environment,the comfort of the living environment and the quality of the urban ecological environment can be improved.Looking ahead,further research and exploration are needed to promote the coordinated development of urban development and environmental protection.
