摘要
分析广州迈向国际大都市过程中大气环境SO2浓度和酷热两个因子对健康的影响.研究表明广州冬季高浓度下死亡比低浓度多10%,夏季酷热天气(高于34℃)下死亡比常日多10%,未来广州大气污染物种类及浓度将增加,气候和市区变暖、夏季暑期延长酷热难挡.必须严格控制污染排放,改善能源结构,加强绿化;城市规划、布局和建筑设计要考虑到由于全球变暖和城市热岛可能造成更严重的酷暑;
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.
