摘　　要：目的了解南水北调东线工程输水干线高邮段调水前钉螺分布和血吸虫病流行现状。方法选择南水北调东线工程输水干线高邮段大运河、三阳河及其两岸3 km范围,以及输水干线毗邻的高邮湖区为监测区,采用常规法进行钉螺和人畜血吸虫病监测。同时在大运河和三阳河各设立3个水体钉螺监测点,采用网捞法和稻草帘诱螺法进行监测。结果2006-2012年南水北调东线工程高邮段未查出感染性钉螺以及当地感染的血吸虫病人和病畜;大运河钉螺面积呈下降趋势,三阳河未发现钉螺。水体钉螺监测点打捞漂浮物270 kg,投放稻草帘720块,均未发现钉螺。结论南水北调东线工程高邮段残存钉螺未发现北移扩散。Objective To understand the endemic situation of schistosomiasis and the distribution of Oncomelania hupensis snails in Gaoyou sections in the east route of the South-to-North Water Diversion Project before water transfer. Methods The Grand Canal,the Sanyang River and the range of 3 kilometers of both sides of the rivers were chosen as the surveillance area in the Gaoyou sections in the east route of the South-to-North Water Diversion Project,and the Gaoyou Lake area adjacent to the east route was also chosen as the surveillance area. The human and livestock schistosomiasis and Oncomelania hupensis snails were monitored by the conventional method. Three underwater snail surveillance sites were set up in the Grand Canal and the Sanyang River respectively,and the net salvage method and the method of attracting snails with rice straw curtains were used to survey the snails underwater in the surveillance sites. Results The schistosome infected snails,the human and livestock schistosomiasis were not found in the Gaoyou sections in the east route of the South-to-North Water Diversion Project from 2006 to 2012. The snail areas were on the decline in the Grand Canal. The snail was not found in the Sanyang River. A total of 270 kg floatage was refloated and 720 pieces of rice straw curtains were placed in the surveillance sites,and there were no snails in the floatage and the rice straw curtains. Conclusion There is no evidence showing that the snails spread to northward in the Gaoyou sections in the east route of the South-to-North Water Diversion Project.
