中文摘要：

目的探讨舟山海岛气象因素与发热伴血小板减少综合征（SFTS）流行的关系。方法收集舟山海岛地区2011-2014年SFTS发病资料及气象资料,采用圆形分布法分析SFTS发病高峰,以及单因素相关分析和多元逐步回归分析方法分析海岛各气象因素与SFTS发病的关系。结果舟山海岛SFTS的发病具有集中趋势（Z=40.8045,P〈0.01）,发病高峰日为6月22日,高峰期为6月13日-8月30日;SFTS发病与月平均大气压呈负相关关系,而与月平均气温及月平均相对湿度均呈正相关关系,且均具有统计学意义（均P〈0.05）;多元逐步回归方程中只有相对湿度进入,决定系数R2=0.590。结论舟山海岛SFTS发病存在季节性高峰,相对湿度可能对SFTS的发病具有重要影响。

英文摘要：

Objective To explore the relationship between meteorological factors and the epidemiology of severe fever with thrombocytopenia syndrome（SFTS） in islands. Methods Data was collected from the incidence of SFTS and meteorological materials in Zhoushan islands, 2011-2014. The seasonal peak was analyzed with circular distribution method, and the relationship between monthly meteorological factors and incidence of SFTS was analyzed with simple correlation and multi-stepwise linear regression. Results The incidence of SFTS in Zhoushan islands had central tendency（Z=40.8045,P0.01）,the peak date was 22 th June, the peak was from 13 th June to 30 th August; The incidence of SFTS showed negative correlation with average atmospheric pressure, while positive correlation with monthly average temperature and monthly average relative humidity monthly, and they all had significant（P〈0.05）; Only monthly average relative humidity enter the multi-stepwise regression and the coefficient of determination（R2） was 0.590. Conclusion The incidence of SFTS in Zhoushan islands has seasonal peak, and it is correlated with relative humidity.
