摘　　要：血吸虫病是一种危害人类健康的重大疾病,钉螺是血吸虫唯一中间宿主,对血吸虫病传播具有重要影响,收集了《全国血吸虫病疫情通报》等中长江中下游5省份在1999—2018年间钉螺孳生面积长时间序列数据。运用Manner-Kendall检验方法对5省份钉螺面积在时空上的变化特征进行了分析。空间分析中湖南湖沼型钉螺面积构成比上升,湖北和江西湖沼型钉螺呈有小幅度的下降,安徽湖沼型钉螺有明显下降趋势,江苏无稳定的变化趋势。时间分析中江苏、安徽、湖北湖沼型钉螺面积有下降趋势,其中湖北的下降趋势不显著,而江西、湖南无显著的上升趋势。江苏和湖北湖沼型钉螺面积突变年份分别为2010年和2017年,安徽省无明显突变,湖南湖沼型钉螺面积突变点在2001—2002年之间,江西湖沼型钉螺面积突变年份为2002年。长江中下游钉螺孳生面积时空变化规律研究,结果可为控螺工作提供依据。Schistosomiasis is one of the major communicable diseases,which seriously impacts human health,Oncomelania hupensis snail is unique intermediate host of Schistosoma japonicum as well as posts significant influence on schistosomiasis transmission.The long-term serial data of oncomelania snail area in the Middle and Lower Reaches of the Yangtze River in the Schistosomiasis situation in People′s Republic of China,were collected from 1999 to 2018.The spatial and temporal variation characteristics of oncomelania hupensis area in five provinces were analyzed by Manner-Kendall test.In the spatial change,the area composition ratio of lake-and-marshland regions in Hunan increased,while that in Hubei and Jiangxi showed a slight decline.The lake-and-marshland snails in Anhui showed a significant downward trend,while Jiangsu showed no stable trend.In the spatial change,the area of lake-and-marshland snails in Jiangsu,Anhui,and Hubei showed a downward trend,among which the downward trend in Hubei was not obvious,while the upward trend in Jiangxi and Hu′nan had an upward trend but the trend was not obvious.the year of the sudden change in the area of the lake and marshes in in Jiangsu and Hubei were 2010 and 2017;There was no significant mutation in Anhui Province;the mutation point of the lake-and-marshland snails in Hu′nan was between 2001 and 2002;the mutation year of the lake-and-marshland snails in Jiangxi was 2002.This paper studies the temporal and spatial changes of the snail breeding area in the middle and lower Yangtze River,and the results can provide a basis for the elimination of snails in different types of distribution areas.
