摘　　要：目的探讨湖南省平江县的慢性支气管炎(慢支)死亡率与气象因素的关系。方法收集平江县2009年1月至2011年12月慢支的死亡数据、人口数据及同期气象数据,利用Spearman相关和主成分分析方法探讨慢支死亡率与气象因素的关系。结果大于45岁的人群慢支死亡率显著升高,是该研究区的敏感人群;50岁以上各年龄段人群中男性慢支死亡率均高于女性;敏感人群慢支死亡率在冬春季较高,且与气温、气压、水汽压、日照时数和风速显著相关。结论平江县45岁以上人群为慢支敏感人群,慢支死亡率具有显著的季节性差异和性别差异,气温、气压、水汽压、日照时数和风速是影响敏感人群慢支死亡率的主要气象因素。Objective To investigate the relationship between chronic bronchitis mortality and meteorological factors in Pingjiang County,Hunan Province,China. Methods The death data of chronic bronchitis,demographic data and corresponding meteorological data from January 2009 to December 2011 in Pingjiang County were collected and analyzed using the Spearman correlation and principal component analysis. Results Chronic bronchitis mortality of population over the age of 45 was significantly increased and regarded as susceptible population. Chronic bronchitis mortality of male was higher than that of female in population over the age of 50. Chronic bronchitis mortality was higher in winter and spring,and had significant correlations with temperature,barometric pressure,vapor pressure,sunshine time and wind velocity. Conclusion Population over the age of 45 is regarded as susceptible one of chronic bronchitis in Pingjiang County. Chronic bronchitis mortality has significant differences in season and gender. Temperature,barometric pressure,vapor pressure,sunshine time and wind velocity are the main meteorological factors.
