摘　　要：目的了解合溪水库主要水系钉螺分布与扩散情况,评价合溪水库血防工程控制钉螺的效果。方法采用草帘诱螺法在合溪水库主要水系不同区域水体诱捕钉螺,在水库网捞法打捞漂浮物查找钉螺,分析合溪水库主要水系水体螺情变化情况。结果投放草帘1 800条,在南溪源头诱获37只钉螺,其余区域未诱获钉螺。水库库区打捞漂浮物5 870 kg,未发现钉螺。结论合溪水库血防项目有效阻止了钉螺扩散,但上游仍有钉螺孳生,需加强水库区域的钉螺监测与控制。objective To understand the status of Oncomelania hupensis snail distribution and diffusion in main drainages of Hexi Reservoir and evaluate the snail control effect of the schistosomiasis control engineering of Hexi Reservoir. Methods The O. hupensis snails were investigated by using the straw curtain method and fishing net method in different areas of the main drainages of Hexi Reservoir, and the results were analyzed, Results A total of 1 800 straw curtains were used and 37 snails were found in Naxi stream. Totally 5 870 kg floats were salved and no snails were found. Conclusion The schistosomiasis con- trol engineering of Hexi Reservoir is effective in the prevention of the snail diffusion, but there are still snails in the upstream. Therefore, the snail surveillance and control need to be strengthened.
