摘　　要：目的探讨北京市2004-2013年肾综合征出血热时间分布特征。方法采用集中度与圆形分布分析方法对北京市2004—2013年肾综合征出血热发病情况进行时间聚集性分析。结果2004—2013年北京市肾综合征出血热共报告450例，发病时间主要集中在春季；季节性分布M值为0．40，具有一定的季节分布特征；圆形分布分析显示：发病高峰在4月9日，流行期为1月23日至6月27日。结论集中度法和圆形分布法可以较好地分析北京肾综合征出血热时间分布特征。Objective To explore seasonal distribution characteristics of the hemorrhagic fever of re- nal syndrome（HFRS） from 2004 to 2013 in Beijing. Methods Concentration degree and circular distribu- tion methods were used to analyze seasonal distribution characteristics for HFRS incidence from 2004 to 2013 in Beijing. Results A total of 450 cases for HFRS were reported from 2004 to 2013 in Beijing. The onset time mainly concentrated in the spring. The M value on behalf of seasonal distribution characteristics was O. 40, which means seasonal concentration characteristics. Circular distribution analysis showed that the peak of HFRS was on April 9 and epidemic periods of HFRS was from January 23 to June 27. Conclusions Concentration degree and circular distribution methods can be used to analyze seasonal distribution charac- teristics of HFRS effectively in Beijing.
