| 摘 要： | 手足口病是一种常见传染病。近几年在我国多次暴发且发病人数显著增加,引起了我国政府和社会各界的广泛关注。目前,对手足口病的研究主要集中在医学领域,而在宏观尺度上的时空分布特征研究及其重点地区分布研究等方面均较少。本文探索应用地理信息系统(GIS)的工具和方法,对2008-2009年中国疾病预防控制信息系统收集的手足口病监测数据进行统计计算、空间可视化和空间分析,得到我国手足口病疫情的时空分布与动态变化特征。研究表明:(1)尽管全国均有手足口病的报告病例,但各省之间发病情况差异较大,且区域内的发病情况也存在较显著差异,一般在人口密度和人口流动性均较大的城市疫情较严重;(2)手足口病在我国的流行高峰期为4-7月,比国外相关研究中的描述提前了一个月;(3)5-6月,我国手足口病的高发区分布明显由南向北移动。(4)2008-2009年,我国手足口病患者98%以上为托幼儿童、散居儿童和学生。鉴此分析,本文提出了具有时间、空间和人群针对性的防控手足口病暴发流行的科学建议。

| Abstract: | Hand-foot-mouth Disease（HFMD） is a common infectious disease which causes by a variety of enteric viruses.In recent years,outbreaks of HFMD have been repeatedly and the diseased population has obviously increased in China,these caused our government and society＇s widespread attention.For the present,most of the HFMD studies focus on medical field,and research on spatial and temporal distribution characteristics at the macro-scale is rare.Taking into account of this situation,this paper based on medical geography theories,with geographic information systems（GIS） as the analysis tool,studied HFMD cases（2008-2009） from the China Disease Prevention and Control Information System.The research process is as follows： firstly,edits statistical data,and calculates the number of reported cases,the average morbidity,the mortality rate and so on in unit time by province;and then inducts it into database and associates with the Administrative Map of China in shapefile format in order for spatial visualization and spatial analysis.The research obtains following conclusions：（1）the serious area of HFMD epidemic situation in 2008 concentrated in three regions： the three northern provinces/city（Hebei,Beijing and Shanxi）,the three southern provinces/autonomous region（Guangdong,Guangxi and Hainan）as well as the eastern provinces/city（Zhejiang,Shanghai and Anhui）;（2） the number of reported cases,morbidity and mortality have remarkable differences between various provinces： the number of reported cases concentrated in eastern and southern of China,and the Qinghai-Tibet Region and the Northwestern Region are few;（3） HFMD in China is ahead of time for one month compared with conventional epidemic peak（April to July）;（4） in most provinces,the number of reported cases increased sharply in April,and started to reduce significantly in August;（5） the distribution of high incidence moves obviously to the north between May and June.The results help to provide a scientific basis for prevention and control of HFMD outbreak and epidemic,also help for further studies focusing on the correlation of HFMD and geographical factors. |
