| 摘 要： | 本文研究了山丘型血吸虫疫区——仁寿县钉螺数量和分布特征。活螺密度为4.71只/0.11m2(2006年)和5.22只/0.11m2(2005年);活螺框出现率为34%(2006年)和39%(2005年)。活螺框出现率和活螺密度呈线性关系,表明钉螺的分布和数量存在特定的环境条件。钉螺主要分布在荒坡、沟渠和河滩等处,数量较大,这些土地利用类型为血吸虫病生态防治的重点地段。

| Abstract: | The feature of quantity and spatial distribution of snails in Renshou County, a schistosome prevailing mountainous and hilly region was studied in this paper. The density of living snails was 4.71/0.11m2 (in 2006) and 5.22/ 0.11m2 (in 2005), and the occurrence of living snails was 34% (in 2006) and 39% (in 2005). The occurrence was linearly related to the density of living snails, indicating that the quantity and distribution of snails requires special environmental conditions. Snails mainly occur in barren slopes, canals and riverbanks with a large quantity, these types of land uses are the key locations for taking ecological measures to prevent schistosomensis. |
