应用地理信息系统对石家庄市手足口病时空特征的分析

Analysis of the space-time characteristics of hand-foot-mouth disease in Shijiazhuang through geographicinformation system

目的应用地理信息系统（GIS）技术分析石家庄市手足口病（HFMD）时空分布特征。方法收集石家庄市2009年至2011年HFMD疫情资料，建立GIS数据库，应用PHGIS软件绘制专题地图，分析时空分布特征。结果石家庄市2009年至2011年HFMD疫情呈现散在发生但局部集中、发病位次逐年交替上升、高发地理区域互补现象；2009年至2011年全市总体发病水平呈下降趋势，同时存在地区差异；HFMD高发聚集区随时间发生转移。结论运用GIS技术能直观显示HFMD疫情的时空分布特征，为进一步掌握HFMD流行规律、及时采取有效防控措施提供科学依据。

Objective To analyze the space-time characteristics of hand-foot-mouth disease （HFMD） in Shijiazhuang by using geographic information system （GIS）. Methods The data of HFMD during 2009 to 2011 in Shijiazhuang were collected and GIS database was created. Special map was drawn by PHGIS software to analyze the space-time characteristics of HFMD in Shijiazhuang. Results The epidemic situation of HFMD in Shijiazhuang appeared sporadic with local centralization. The attack ranked alternately rise year after year and high epidemic areas were geographically complimentary. Overall epidemic levels tend dropping from 2009 to 2011 and there were differences among areas. The high-attack areas of HFMD changed over time. Conclusions GIS can provide direct-viewing of the space-time characteristics of HFMD and further understand the prevalence of HFMD, which could help to provide the scientific basis of HFMD control in Shijiazhuang.
