論文概要: With the rapid development of global urbanization, urban thermal environment problems have become more and more prominent. Based on multi-source data, this study conducted urban thermal environment research on two cities with different development models from three urban scales. Remote sensing data was used to explore the spatiotemporal characteristics of surface urban heat islands from the urban macroscale. Then, combined with land use data and local climate zone (LCZ) classification system, the intensity of industrial heat island and the effect of urban structure on land surface temperature (LST) around elementary schools were analyzed from the urban mesoscale. Finally, through field measurements, questionnaires and software simulations, the thermal benchmark suitable for the factory area was constructed, and the impact of urban morphology on the microclimate around elementary schools was analyzed.
In Chapter 1, the background and purpose of the research were elaborated.
In Chapter 2, multi-source data research methods were introduced.
In Chapter 3, the urban structure identification method was introduced. Combined with the LCZ classification results, the spatial characteristics of urban structure were investigated.
In Chapter 4, the spatial heterogeneity of LST was explored. In addition, urban heat islands and industrial heat islands in different seasons were analyzed.
In Chapter 5, the random forest regression model was used to explore the relationship between LCZs and seasonal LST around elementary schools and the relative importance of each LCZ.
In Chapter 6, the influence of built environments in factory areas on human thermal sensation and thermal comfort was investigated. Combined with thermal comfort indices Physiological Equivalent Temperature and Universal Thermal Climate Index, 12 observation sites in factory areas were evaluated to establish the outdoor thermal benchmark suitable for the factory area.
In Chapter 7, differences in air temperature between different types of elementary schools were compared through measured data, and the impact of urban morphology on the microclimate around elementary schools was attempted to be elucidated based on field measurements and ENVI-met simulations.
In Chapter 8, the critical summary of each chapter was concluded.
