摘　　要：目的运用空间统计学的方法分析2014年贵州省乙型病毒性肝炎(乙肝)报告发病率空间分布特征,探讨其空间聚集特征,为乙肝防治策略提供科学依据。方法综合乙肝报告发病率、空间自相关分析法和空间扫描统计量,以县区级为单位对2014年乙肝监测数据进行分析。结果 2014年贵州省乙肝报告发病率存在空间自相关性(P=0.004);局部空间自相关分析发现区域内存在"High-High"局部空间正关联模式(P<0.05)(即热点区域,分布于遵义市和黔南州的部分县区)、"Low-Low"局部正空间关联模式(P<0.05)(即冷点区域,分布于黔西南州、安顺市、六盘水市、铜仁市的部分县区);单纯扫描统计量结果显示乙肝发病最大可能聚集区域为独山县、荔波县、三都县、平塘县、都匀市5个县(市)(RR=2.11,P=0.001),其均分布于黔南州。结论 2014年贵州省乙肝报告发病率呈非随机空间分布,具有空间聚集性,黔南州和遵义市存在乙肝高发病聚集区域,是今后贵州省乙肝防控重点区域。Objective To analyze the spatial distribution of hepatitis B in Guizhou province ,2014, and to provide evidence for hepatitis B control and prevention. Methods Based on the data from the communicable disease surveillance network system of China Center for Disease Control and Prevention,we used spatial autocorrelation method and scan statistics to identify the spatial distribution of hepatitis B in Guizhou province at the level of the county. Results Reported hepatitis B incidence of Guizhou in 2014 had spatial autocorrelation statistically （P = 0. 004）. Local indicators of spatial association （LISA） identified High -High pattern areas （ part of Zunyi and Qiannan） and Low - Low pattern areas （ part of Qianxinan, Anshun, Liupanshui and Tongren）. Scan statistics results revealed that the most likely clustering of high hepatitis B incidence was in Dushan, Libo, Sandu, Pingtang,Duyun （RR = 2.11, P = 0. 001 ）. Conclusion The spatial distribution of the incidence of hepatitis B in Guizhou province is not random and shows spatial clustering. The clustering of the disease is found in Qiannan and Zunyi, indicating hepatitis B control and prevention should be strengthened in these areas.
