Global climate change may intensify urban heat islands with implications for local heat stress, morbidity and public health. In this study, according to the risk assessment framework of the Fifth Assessment Report of IPCC, we analyzed the patterns of risks in Taipei Basin area under heatwaves. We used Landsat TM satellite images at July 21, 2007, to convert land surface temperature. Then we estimated the heat index of the study area with the regression of land surface temperature and the data of meteorological station. We also proposed a risk of heat assessment framework under heat stress, including exposure and vulnerability indicators. Spatial interpolation is used to calculate the duration and intensity of extreme heat events, and further, the data was divided into sensitivity indicators to assess the vulnerable population and the adaptive capacity indicators to evaluate the extent to which the heat impact was reduced. Finally, we used the data of outpatients of heat-related diseases from the National Health Insurance Database to analyze the relationships between socio-economic factors and heat-related morbidity in Taipei Basin area. To better understand the patterns of the risks of extreme heat events, we suggested some improvements to the area which were relatively lack of medical resources. Our results suggest that (a) the outpatients of heat-related diseases had a significant positive correlation with the heat index in Taipei Basin area under extreme heat events; (b) there were four districts in high risks of heat stress, including Sanchong, Datong, Wanhua and Yonghe District; (c) different from some prior studies, the indicators in this study reflected the empirical risks of the outpatients of heat-related diseases during extreme heat events. The results of the study could be used to help modifing the urban development policies, and finally reached a just, healthy, security and sustainable society.
