利用南京市2004-2009年居民死亡资料和同期气象资料,分析了2004-2009年南京市呼吸系统和循环系统疾病死亡人数的年内变化规律,在计算3种人体舒适度基础上研究了上述两大系统疾病死亡人数与气象因子(包括气象要素及人体舒适度在内)之间的关系。结果表明:南京市年内气温呈“Λ”型分布,人体舒适度呈“M”型分布,呼吸系统和循环系统疾病死亡人数的年内分布正好与气温分布呈反位相,即两大系统疾病死亡人数整体上均呈现出冬半年多,夏半年少的分布特点,说明寒冷是诱发两大系统疾病患者死亡的主要气象因素。值得注意的是,两大系统疾病死亡人数在8-9月份又呈现出一个死亡小高峰,这主要是由于高温和季节交替所造成的。呼吸系统和循环系统疾病逐日死亡人数与气象因子显著相关,并对气象因子的响应具有一定的持续效应和滞后性。
Using the death data and corresponding period meteorological data during 2004-2009 in Nanjing City, the annual variation law of deaths from the respiratory and circulatory system diseases was analyzed, and the relationships between deaths from the two disease systems and meteorological factors (including meteoro-logical factors and human comfortable indexes) were studied, based on three human comfortable indexes. The results show that temperature distribution looked like a ’Λ’ and human comfortable indexes distribution looked like an ’M’ in a typical year, while the distribution of deaths from the two disease systems were in an anti-phase relation with temperature, i.e. it demonstrated that deaths during the winter half year were more than the summer half year. It could be considered that coldness was the main factor causing deaths from the two system diseases. It was worth noting that there was a small peak of deaths from August to September, which was mainly thanks to the high temperature and seasonal alternation. The study also found that a significant correlation existed between deaths from daily diseases of the two systems and meteorological factors; besides, deaths from the two system daily disease had persistent effects and hysteretic quality responding to meteorological factors.
