回顾了血吸虫病防治历史，分析了我国血吸虫病防治取得的成就和存在问题，提出了林业生态工程防治血吸虫病的理论，并以长江中下游血吸虫病流行滩地为研究对象，以实施抑螺防病林业生态工程，改变滩地环境因子，减少甚至消灭血吸虫病的唯一中间宿主钉螺，增加环境及经济效益为主线，对长江中下游滩地的分布，钉螺密度和钉螺分布及其与环境因子的关系，滩地植被演替方式，现有滩地植被类型的改造方式及其抑螺林农复合生态系统的结构与功能等进行了系统研究。

This paper reviewed the history of schistosomiasis prevention, analysed the accomplishment and problems of schistosomiasis prevention in China, and brought forward the theory of the beaches snails outwipping forest ecological engineering. The study focused on beaches with severe schistosomiasis probanation in the middle and lower reaches of the Yangtze River in order to carry out snail outwipping forest ecological engineering, to change the environmental factors on beaches, to reduce or eliminate the snails(oncomelania)-the only host of Schistomata japonica , and to enhance the environmental and economical benefits. Thesis systematically studied the distribution of beaches along the middle and lower reaches of the Yangtze River, the relationship between environmental factors and distribution and density of oncomelania, the successional pattern of the beach vegetation, the transformation approaches and bio-productivity of the existing beach vegetation types, and the structure and function of the snail outwipping agroforestry ecosystems.
