摘 要：
本文在解析山丘区钉螺分布特征的基础上、提出了浅丘区的抑螺林分类及体系布局。结果表明:(1)该流域钉螺平均密度为4.05只.0.11 m-2,活螺框出现率为34.00%;(2)钉螺密度和活螺出现率均以林地最低,旱地其次,而水田、河滩、荒坡和沟渠较高;(3)不同环境类型活螺出现率依次为:洲滩>湖滩>沟>河>林地>塘。该区域的抑螺防病林可分为河渠抑螺林、坡地抑螺林、农田抑螺林和多功能抑螺林四种类型、各种林分类型在树种选择、组成、功能上各有不同,但抑螺林的布局必须以降低钉螺密度、减少人畜感染机率为主要目标,同时兼顾经济及生态方面的效益。

摘 要：
Based on oncomelania distribution characteristics in purple shallow hilly areas of Sichuan,types and layout of oncomelania-controlling forest is put forward in the paper.The results have shown that:(1)The mean density is 4.05 snails·0.11 m-2,and the living snail frame occurrence rate is 34% in the watershed;(2)The regularity of oncomelania density is that paddy fields>irrigation canal>wastelands>beaches>arable lands>forestlands(3)Another regularity of occurrence rate of living snail frame is that paddy fields>beaches>wastelands>irrigation canal>arable lands>woodlands.According to the law of distribution of the oncomelania in the hilly and mountains district,oncomelania-controlling forest is divided into four types,namely,river-ditch mode,slope mode,field mode and multifunction mode.Each mode is varied in aspects of tree species,composition and function.Reducing oncomelania density and infection rate of snail fever is a chief object of planting oncomelania-controlling forest,and at the same time,attention must be paid to benefits of ecology and economy.
