摘要
选取南京地区1961年1月1日至2012年12月31日逐日地面气象观测资料，采用“黄金分割法”计算体感温度，分析南京地区近52年舒适度特征；选取2005年1月1日至2008年12月31日逐日循环系统疾病死亡人数资料和同期气象资料，分析南京市2005—2008年舒适度和体感温度特征及其与循环系统疾病死亡人数的关系。结果表明，1961-2012年南京市热不舒适期、舒适期日数呈现上升趋势，而冷不舒适期日数呈显著减少趋势，变化率为3．2d／10a；4月上旬至5月中旬和10月为舒适期；体感温度在20世纪中期之后表现为明显的上升趋势，增加率为0．3℃／10a；2005-2008年舒适度以微冷和舒适为主；死亡高峰日多出现在冷不舒适日，2008年初死亡高峰日持续时间较长，且与天气灾宵过程发生时间存在7～9d的滞后。
Based on a new algorithm to calculate apparent temperature, a novel criterion to evaluate human comfort levels was devised and applied to calculate climate comfort by using daily routine surface observational data from 1 January 1961 to 31 December 2012. Based on daily mortality from circulatory system disease and Nanjing meteorological data from 1 January 2005 to 31 December 2008, characteristics of comfort levels and apparent temperature during this period were analyzed. Then, the relationship between comfort levels and mortality was analyzed. The hot uncomfortable days show an upward tendency, however cold uncomfortable days show a downward tendency （ 3.2 d/10a）. Early April to mid-May and October are two comfortable periods in Nanjing. Mean apparent temperature has a rising tendency （0.3 ℃/10a） after 1995. Main comfort levels are comfort and slightly cold in Nanjing during the period of 2005 2008. Peak days of mortality from circulatory system disease occur in cold uncomfortable days. There was a successive high mortality period in 2008, which has a 7-9 d lag compared with the weather disasters process during this period.
