This paper presents the impacts of atmospheric environmental SO 2 concentration and intense heat on the people′s health during the process to build Guangzhou into an international metropolis. Basing on the statistical analysis of human mortality in summer and winter

it is found that deaths from heigh daily SO 2 concentration are 10 percent more than those from low daily SO 2 concentration in winter and deaths from "hot day" with maximum temperature heigher than 34℃ are 10 pencent more than those from ordinary day′s temperature in summer. Because of the pollutant varieties and pollutant concentrations will increase

the climate and urban district will become warmer

and the summer day will become longer and extremely hot

in order to build Guangzhou into an international metropolis

it needs to control the pollutant′s emission strictly

to improve the energy structures and plant more trees in and around the city. On city planning

distribution and designing of architecture

it must be considered the global warming and the intense heat due to city hot island. It needs to improve the medical facilities and establishing both air pollution forecast system and medical weather forecast system.
