Abstract
Global climate change has intensified extreme climate events such as torrential rain/snow, heat waves, and droughts. Among climate disaster events, extreme heat can bring long and intensified heat waves and seriously impact the human living environment and ecological habitat. However, extreme heat may have inconsistent impacts on various geographical environments, and such extreme heat might impact human health differently among various locations and climate zones. Therefore, this study applies Moderate Resolution Imaging Spectroradiometer (MODIS) data to produce 2014-2018 land surface temperatures and further applies spatial analysis to categorize areas into absolute and relative heat areas in the Taipei metropolitan area in Taiwan. A comparative analysis is then conducted based on ordinary least squares (OLS) and geographically weighted regression (GWR) to explore the spatial heterogeneity of changing heat environments in the study area. Although the OLS results show that mixed use has the greatest influence on heat, whereas green space and barren land have the highest negative effect on heat, the GWR analysis shows that the coefficients of every land use type demonstrate different spatial patterns. These spatial patterns can be applied as a reference for the mitigation plans to reduce the effects of heat.
