摘　　要：选择湖北省江陵县颜家台灌区和公安县合顺垸灌区两个典型灌区为研究对象,分析了以渠系硬化衬砌及疏浚为主的灌区水利血防工程实施前后螺情、血吸虫病病情的变化情况,评估了灌区水利血防工程控制血吸虫病的效果。结果表明:以硬化衬砌及疏浚为主的灌区水利血防工程实施后,颜家台灌区内有螺面积平均下降33.34%,活螺平均密度下降22.01%,人群感染率下降100%;合顺垸灌区内有螺面积平均下降100%,活螺平均密度下降100%,人群感染率下降100%。这两个典型灌区水利血防工程对降低活螺密度、控制血吸虫病有很好的效果。研究成果为进一步提高我国血吸虫病流行区灌区控螺防病水平提供了实践参考,对于支撑加快消除血吸虫病目标和实现健康中国目标具有重要意义。Choosing the Yanjiatai Irrigation District in Jiangling County and the Heshunwan Irrigation District in Gong'an County as typical study areas,this paper analyzes the changes in snail populations and schistosomiasis disease before and after the implementation of the water conservancy schistosomiasis control project,primarily focusing on canal hardening and dredging.The effectiveness of these irrigation projects in controlling schistosomiasis is evaluated.The results show that after the implementation of the schistosomiasis control projects,the area with snails within the Yanjiatai Irrigation District decreased by an average of 33.34%,the average density of live snail decreased by 22.01%,and the population infection rate decreased by 100%.In the Heshunwan irrigation area,the average area with snails decreased by 100%,the average density of live snails decreased by 100%,and the population infection rate decreased by 100%.These two typical irrigation projects have a significant effect on reducing the density of live snails and controlling schistosomiasis.The research findings provide practical references for further improving the level of snail control and disease prevention in irrigation areas of schistosomiasis-endemic areas in China,and are of significant importance for supporting the goal of accelerating elimination of schistosomiasis and achieving“healthy China”.
