利用南京地区2005-2008年冬半年(10月-次年3月)逐日气象资料和同期呼吸系统疾病死亡人数资料,采用“黄金分割法”计算体感温度,划分舒适度指数的方法,分析冬半年呼吸系统疾病死亡人数与舒适度(体感温度)之间的关系,归纳总结了诱发冬半年呼吸系统疾病患者死亡的天气类型.结果表明,呼吸系统疾病死亡人数随着平均体感温度的降低而升高,当冬半年体感温度达12℃和2℃C时,为南京地区呼吸系统疾病的警戒温度,呼吸系统疾病患者需注意防范.极端低温的天气条件是呼吸系统疾病患者死亡的高发期,尤其是舒适度等级为微冷时,微冷日数约占死亡高峰日总数的61.1%;诱发冬半年呼吸系统疾病患者死亡的天气类型可以分为6种,冷空气活动引起的气温低和气温日较差大是导致冬半年呼吸系统疾病患者发病、病情加重或死亡的主要原因.
Based on the daily meteorological data of 2005-2008 in the winter of 2005-2008 (from October to March next year) and the data of deaths from respiratory diseases in the same period of 2005-2008 in Nanjing, the “golden section method” was used to calculate the somatosensory temperature and the comfort index was analyzed. The relationship between the number of deaths from respiratory diseases and comfort (somatosensory temperature) in the winter half year was summarized and the types of weather induced death in respiratory tract diseases in winter were summarized.The results showed that with the decrease of average somatosensory temperature When the somatosensory temperature reaches 12 ℃ and 2 ℃ C in the winter half year, it is the alarming temperature of respiratory system diseases in Nanjing, and the patients with respiratory diseases should pay attention to prevent it.The extreme low temperature weather conditions are the high risk of death in patients with respiratory diseases, Especially when the comfort level is slightly cold, the number of cool days is about 61.1% of the total number of death peaks. The types of weather that induce the death of patients with respiratory diseases in winter can be divided into 6 types: low temperature caused by cold air activity and air temperature day Poor is the main cause of illness, exacerbations or death of patients with respiratory diseases in the winter half year.
