摘要
目的从空间自相关角度分析我国2004-2013年病毒性肝炎流行状况。方法运用ArcGIS10.2软件空间自相关分析方法对中国病毒性肝炎疫情数据进行空间显示和统计分析。结果病毒性肝炎发病率空间分布图和空间自相关分析结果显示,2004-2013年病毒性肝炎发病存在高发区和低发区,存在空间聚集性;局部Local Moran's I自相关分析结果表明,青海、宁夏、甘肃为高高值(HH)聚集区,山东、江苏为低低值(LL)聚集区。结论我国病毒性肝炎具有明显的地域分布,存在空间聚集性,对其形成原因和相关机制进一步探索。
Objective To analyze the epidemic characteristics of viral hepatitis in China in 2004-2013. Methods Using ArcGIS10. 2 software spatial autocorrelation to analyze viral hepatitis epidemic in China. Results The incidence maps of viral hepatitis and spatial autocorrelation analysis showed that the spatial aggregation existed in viral hepatitis during 2004-2013.Local Moran＇s I spatial autocorrelation analysis identified the＂high incidence region＂and＂low incidence region＂. Conclusion The incidence of viral hepatitis is obviously geographical distribution in China. Spatial clustering nature of viral hepatitis appeared in China between 2004-2013. To deal with the formation reasons and related mechanism,further explore is needed.
