摘　　要：目的了解长江下游洲岛滩涂湿地蓄水养殖灭螺项目效果和效益。方法选择长江下游丹徒段洲岛型血吸虫病流行区滩涂湿地实施蓄水养殖灭螺,常规法监测调查项目实施前后钉螺孳生情况,以评估项目控制和消除钉螺效果。同时采用静态效益-费用比率法对其中2个蓄水养殖灭螺项目进行费用-效益分析。结果长江下游丹徒段洲岛型流行区滩涂湿地的7个蓄水养殖项目实施后第1年即全部消除了钉螺;项目实施后平均每个项目每年节约查灭螺费用6.92万元;南号10组滩和五套6~14滩蓄水养殖项目年净效益分别为203.94万元和95.5万元,年净效益费用比分别为1.09∶1和1.07∶1。结论在长江下游洲岛型血吸虫病流行区滩涂湿地开展蓄水养殖灭螺可快速消除钉螺孳生,且经济效益明显,但需综合考虑湿地生态保护和长江防洪安全等因素。Objective To evaluate the effect and the benefits of the projects of water storage and aquaculture on Oncomelania hupensis snail control in the tidal flats wetlands of islet-beach type area of lower reaches of the Yangtze River. Methods The projects of water storage and aquaculture on O. hupensis snail control were implemented in the tidal flats wetlands of isletbeach type of lower reaches of the Yangtze River. The breed situation of the snails was investigated by the conventional method before and after the project implementation and the effect of control and elimination of the snails by the projects were evaluated.At the same time,the cost-benefit analysis of two projects among them was performed by the static benefit-cost ratio method. Re Results All of O. hupensis snails were eliminated in the first year after the implementation of seven water storage and aquaculture projects. The costs of detection and control of snails saved by each project was 69.20 thousand yuan a year on average. The annual net benefits of the＂Nanhao Group 10 beach＂project and＂Wutao Group 6-14 beach＂project were 2 039.40 thousand yuan and 955.00 thousand yuan respectively,and the annual net benefit-cost ratios were 1.09∶1 and 1.07∶1 respectively. Conclu Conclusion The O. hupensis snails could be rapidly eliminated by the water storage and aquaculture,and the economic benefit is obvious,but the wetland ecological protection and flood control safety should be considered in the tidal flats wetlands of islet-beach type area of lower reaches of the Yangtze River.
