【摘要】 对2003年3—6月我国SARS(SeverAcuteRespiratorySyndrome,严重急性呼吸道综合症)发病人数最多的北京、香港逐日病例和有关气象因子进行了对比分析,结果表明:气温、气压的走向和SARS发病率有很好的关系;相对湿度高、云量多和日照少是两地高发期的共同特点;冷空气活动对SARS疫情的流行有诱发推动的作用。通过高发期逐日发病人数和气象要素随基准值变化的对应关系设计了综合指数,分别计算了两地气温因子的高危指标,结果显示,两地日平均气温和日最低气温指标相差了3℃和7℃,两地日最高气温指标均为24～27℃。更多还原

【Abstract】 Based on the daily SARS(Sever Acute Respiratory Syndrome) patients and local meteorological factors in Beijing and Hongkong,we conclude that air temperature and pressure had a high correlation with the incidence of SARS;high relative humidity,cloudy weather and the lack of sunlight were the common meteorological characteristics,and the cold air activities promoted the prevalence of SARS.In this paper we also formed an integrated index based on the corresponding relation of the number of SARS patients and meteorological factor changes,then calculated the high danger index(Zj) of air temperature in Beijing and Hongkong,and results show that daily average temperature and daily minimal temperature indices have a 3℃ and 7℃ differences,respectively,while the maximum temperature index are both 24～27℃ in the two regions.更多还原
