摘要
目的了解石台县钉螺分布现状与特点。方法收集2009年石台县钉螺调查的数据和各螺点的GPS定位数据,建立钉螺分布空间数据库,用Arcgis 9.1绘制电子地图,分析全县钉螺分布现状。结果 2009年全县查出钉螺环境1 133处,其中秋浦河水系占67.4%,黄湓河水系占30.9%,清溪河水系占1.7%;查出感染性钉螺环境24处,其中秋浦河水系占79.2%,黄湓河水系占20.8%;新发现、复现钉螺环境97.2%分布于秋浦河、黄湓河水系。沟渠是钉螺与感染性钉螺分布的主要环境,感染性钉螺环境分布呈动态变化,83.3%分布于疫情控制村。结论全县钉螺分布与水系密切相关,三大水系钉螺分布轻重不一,特点不同,应进行分类防治。
Objective To understand the current situation and characteristic of the snail distribution in Shitai county.Methods The data of snail survey in 2009 were collected,the database was set up,the position of environments of infected snails were located with GPS,the E-map was established with ARCGIS 9.1 and the distribution of snail was analyzed.Results In 2009,1131 snail environments were found in Shitai,and 67.4% were distributed in the Qiupu River,30.9% in Huangpeng River and 1.7% in Qingxi River.24 environments were found with infected snail,and 79.2% were distributed in Qiupu River,20.8% in Huangpeng River.97.2% of the recurrence and new discovery snail environments were found in Qiupu and Huangpen River.The snail and the infected snail were mainly found in the canal in the mountainous areas,and the distribution of infected snails was dynamic changed.83.3% of the environments with infected snail were distributed in the villages which the endemic situation was controlled.Conclusion The distribution of snail is closely related with the river system in Shitai county,and with different characteristics in the three major river systems. Therefore,the measures for snail control should be classified in the county.
