摘　　要：目的探索2004~2011年湖南省血吸虫病流行程度的时空特征和变化规律。方法基于2004~2011年湖南省乡镇血吸虫病流行程度数据库,运用SPSS 17.0及地理信息系统软件(Arc GIS 10.1)描述和分析湖南省血吸虫病流行程度的时空特征。结果 2004~2011年湖南省乡镇血吸虫病流行程度平均赋分值由3.1分下降至2.3分。全局自相关分析显示,2004~2011年乡镇流行程度Moran's I值为0.28~0.44,均高于期望值且具有统计学意义(Z>7.15,P<0.05);局部G统计量热点分析显示,2004~2011年正热点"高-高"(H-H)聚集乡镇主要为垸外有螺水系沿岸乡镇,年聚集乡镇数量为19~33个。结论 2004~2011年湖南省血吸虫病流行程度下降明显,2011年仍处于较高水平。湖南省血吸虫病流行存在明显正向空间自相关和聚集性;正热点"高-高"聚集区域可确定为下一步血吸虫病防治工作的重点。Objective To investigate the spatial-temporal characteristics and changing rules of schistosomiasis in Hunan Province from 2004 through 2011. Methods The endemic characteristics of schistosomiasis were analyzed in accordance with the spatial database on schistosomiasis distribution in Hunan Province between 2004 and 201 using software SPPSS(version 17.0) and ArcGIS(version 10.1). Results The mean level for schistosomiasis in Hunan Province was decreased from 3.1 in 2004 to 2.3 in 2011. Autocorrelation analysis indicated that the infection rate of schistosomiasis ranged from 0.28 to 0.44 bweteen 2004 and 2011 in township by Moran's I value, which was higher than the expected value (Z>7.15, P<0.05). Local G statistics indicated that the positive high-high clustering areas by hotspots from 2004 to 2011 were primarily associated with townships outside the embankment with snail prevalence in water areas, and the annual number of townships with endemic schistosomiasis in the clustering areas was between 19 and 33. Conclusion The endemic level of schistosomiasis was significantly decreased in Hunan Province from 2004 through 2011, though remained at comparatively higher level in 2011, and the endemicity demonstrated significant positive spatial correlation and agglomera? tions. Following tasks on prevention and control of the schistosomiasis in Hunan Province should be targeted in high-high clustering areas.
