中文摘要：

目的：分析2006-2011年湖北省江陵县血吸虫病疫情的时空分布特点。方法收集整理2006-2011年江陵县血吸虫病监测数据，建立空间数据库，导入SaTScan9.1.1软件进行时空重排扫描聚集分析，确定血吸虫病发生的时空聚集性，并采用ArcGIS10.0软件制作风险地图。结果2011年江陵县人群和耕牛血吸虫感染率、钉螺感染率较2006年分别下降了47.67%、93.34%和52.41%。时空聚集性分析显示，2006-2011年上述3个指标在时空分布上均存在聚集性，分别探测出4、3个和4个聚集区域，均分布于垸内。结论2006-2011年江陵县血吸虫病疫情呈现下降态势，探测发现的聚集性区域是该县血吸虫病防治的重点区域。提示，时空重排扫描统计可用于血吸虫病疫情分析。

英文摘要：

Objective To analyze the spatial-time distribution characteristics of schistosomiasis in Jiangling County ,Hubei Province from 2006 to 2011. Methods The surveillance data of schistosomiasis of Jiangling County from 2006 to 2011 were col-lected,and a spatial database was established. The spatial-time permutation cluster analysis was performed by SaTScan 9.1.1 to detect the spatial-time cluster areas of schistosomiasis,and a risk map was drawn by ArcGIS 10.0. Results Compared to 2006, the infection rates of human,cattle and Oncomelania hupensis snails decreased by 47.67%,93.34%and 52.41%,respectively in 2011. The space-time permutation clustering analysis of the infection rates of human,cattle and snails showed 4,3 and 4 clusters,respectively,and all the clustered areas were distributed in inner embankment areas. Conclusions From 2006 to 2011,the schistosomiasis endemic situation presents a decline trend in Jiangling County. The detected cluster areas are the im-portant areas for schistosomiasis control. The space-time permutation statistics could be used in the analysis of endemic situation of schistosomiasis.
