摘　　要：目的了解江苏省2003—2009年甲型肝炎(简称甲肝)的空间分布规律及其影响因素,为相关部门制定科学的预防控制措施提供理论依据。方法收集江苏省2003—2009年甲肝的发病资料,应用Arc GIS 10.0软件分析江苏省甲肝的区域分布特点,并将甲肝发病率与其可能的发病影响因素进行相关分析。结果江苏省甲肝的高危地区主要分布于中部和东南部地区;甲肝发病率与距铁路的远近呈负相关[y=1.189-(1.2E-5)x3,R2=0.977,F=209.245,P<0.001],距铁路越近,甲型肝炎发病率越高;洪泽湖和骆马湖附近甲肝的发病率相对较高。结论江苏省甲肝的流行有明显的地域分布规律,应根据不同地区的流行强度、针对甲肝的流行原因采取有效的预防控制措施。Objective To examine spatial distribution of hepatitis A and its influencing factors in Jiangsu province from 2003 to 2009 and to provide basis for making prevention and control measures of hepatitis A. Methods Based on reported data of hepatitis A cases in Jiangsu province from 2003 to 2009, the characteristics of the distribution of hepatitis A and the relevance between hepatitis A prevalence and its influencing factors were analyzed using geographic informa- tion system. Results Hepatitis A in the province occurred mainly in the central and southeast of Jiangsu province. The incidence of hepatitis A and the distance from the railway station was negatively correlated. The areas closer to the rail- way station had higher incidence of hepatitis A. There was a relatively higher incidence of hepatitis A in areas near Hongze Lake and Luoma Lake. Conclusion The incidence of hepatitis A presents a difference in geographical distribu- tion. Efficient preventive and controlling measures for hepatitis A should be taken according to its epidemic strength and influencing factors in different areas.
