【摘要】 本文以四川省山丘型血吸虫病疫区为研究对象,对四川山丘型抑螺防病林模式构建技术问题进行了探讨,分析提出了山丘型钉螺分布的典型特征,即具有明显的小流域特征、山体广域分布特征和边缘效应分布特征;深入研究了山丘型抑螺防病林的作用机理,提出了控螺、阻螺、驱螺灭螺3种功能;在此基础上,研究提出了抑螺防病林结构模式和以小流域为单元的抑螺防病林体系布局,并调查总结了四川山丘型林业血防工程建设的5个典型模式。更多还原

【Abstract】 Taking the a schistosomiasis epidemic area in a hilly and mountain area of Sichuan Province as the research object,discussion was made on the establishonent technology of forestry model for snail control and schistosomiasis prevention. By the analysis of snail distribution,the obvious characteristics of watershed distribution,wide area distribution along the mountain and distribution of edge effect were brought forward. To further research the mechanism of snail control and schistosomiasis prevention forestry,three functions of controlling,resisting,driving away and killing snails were put forward. On this basis,structure model of snail control and schistosomiasis prevention forestry and forestry system layout with watershed as a unit were proposed,and the 5 typical establishment modes of forestry for schistosomiasis prevention in a hilly and mountain area of Sichuan Province were investigated and summarized.更多还原
