Abstract:

Research is done on risk regionalization of human health in Guangdong Province caused by high temperature & heat wave based on quantitative risk index. The hazard index of high temperature & heat wave, exposure index and vulnerability index (including sensitivity index and adaptability index) of hazard-affected body in Guangdong Province are constructed respectively, from the view of the construction of risk of human health caused by high temperature & heat wave, applying the internationally used risk concepts and analysis methods of natural disasters. The result indicates that the high hazard region is northeast, northwest and central west of Guangdong, while the low hazard region is mainly the littoral of Guangdong; the region of high human health sensitivity is north and west of Guangdong, while the Pearl Delta and the littoral of southeast of Guangdong relatively possess low sensitivity; the region of high human health adaptability is the Pearl Delta, while others possess low adaptability; high risk lies in east, northwest, central west of Guangdong and south of Leizhou Peninsula, and low risk lies in Pearl Delta and the littoral of its west. The risk index could better reflect the risk distribution of human health caused by high temperature & heat wave in Guangdong Province.

Key words: high temperature &, heat wave, human health, hazard, exposure, vulnerability, risk regionalization
