To evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control snails in the rivers connecting with the Yangtze River.
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 snails.
After the projects of the water 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.
The comprehensive measures 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.
评估水利血防工程结合灭螺药物控制长江连通河道钉螺的效果。
选取南京市浦口区朱家山河、七里河、高旺河水利血防工程作为研究对象，采用资料回顾法和现场调查法评估水利血防工程结合灭螺药物控制钉螺的效果。
实施水位控制、混凝土护坡及药物灭螺工程后，工程河段钉螺全部灭光，内陆灌区也未发生钉螺扩散。外滩虽仍有钉螺存在，但钉螺密度降至每平方米1.0只以下。
水位控制、混凝土护坡及药物灭螺相结合的综合措施能有效控制和消灭钉螺，并防止钉螺扩散。
