| dc.description.abstract | This study focuses on the Taoyuan Plateau, investigating the impacts of climate change, land use changes, and population growth on thermal comfort. Through historical data analysis, field observations, and future climate change scenario simulations, this study contains three parts: (1) In-situ observations at the National Central University campus to calculate Physiological Equivalent Temperature (PET) under different pavement conditions, evaluating the benefits of shading on thermal comfort and identifying key factors affecting PET values during the day and night; (2) Analyzing PET changes of the Taoyuan Plateau from 1993 to 2022 in association with changes of land use and population by different clusters to assess their influence on PET values; (3) Calculating projections of PET trends for the Taoyuan Plateau and various pavement types under future climate change scenarios.
The results reveal that daytime PET is primarily affected by mean radiant temperature, while nighttime PET is highly related to wind speed. Historical data of the Taoyuan Plateau show a strong correlation between rising PET and increases in impervious surfaces and population, with impervious surfaces having a particularly significant impact. Future simulations indicate an upward trend in thermal discomfort across all scenarios, with high-emission scenarios potentially reaching ＂very hot＂ levels. This research aims to provide scientific information to support the development of thermal comfort adaptation.
