目的评价通江河道水利血防工程结合药物灭螺控制钉螺效果。方法选择南京市浦口区朱家山河、七里河和高旺河为研究对象,采用资料回顾和现场调查方法,评估通江河道水利血防工程结合药物灭螺控制钉螺效果。结果通江河道实施水位控制、砼护坡水利血防工程及药物灭螺后,工程段钉螺即消除,内陆灌区未发生钉螺扩散,河口外江滩虽然仍保持有钉螺孳生,但钉螺密度大幅下降至1.0只/0.1 m^2以下。结论通江河道水位控制、砼护坡结合药物灭螺综合措施可稳定有效地控制和消除钉螺孳生,阻止钉螺向内陆扩散。
Objective To evaluate the effect of the water conservancy schistosomiasis control projects combined with mollus-cicide to control Oncomelania hupensis snails in the rivers connecting with the Yangtze River. Methods The water conservancy schistosomiasis control projects of Zhujiashan River, Qili River and Gaowang River were chosen as the study objects in Pukou District, Nanjing City. The data review method and field investigation were used to evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control O. hupensis snarls. Results After the projects of the wa- ter level control and concrete slope protection and mollusciciding were implemented, the snails in the project river sections were completely eliminated. The snail diffusion did not happen in the inland irrigation area too. In the outside of the river beach, though the snails still existed, the snail densities plunged below 1.0 snail per 1.0 m^2. Conclusion The comprehensive mea- sures of the combination of water level control, concrete slope protection and mollusciciding can effectively control and eliminate the snails, and prevent the snails from spreading.
