【摘要】 目的探索三峡库区湖北段有无血吸虫病传播的危险因素。方法采用回顾性调查法、类比法和模拟生态实验等方法．结果与结论进一步证实三峡库区湖北段无钉螺生长，但调查表明三峡库区存在着与血吸虫病疫区相似的气候环境、相似的土壤容重和相同的钉螺能吃的植物。说明三峡库区湖北段存在着生长钉螺的基本环境条件。其不生长钉螺的原因尚须进一步研究。更多还原

【Abstract】 Aim In order to explore whether there are the danger factors of epidemic schistosomiasis in Hubei part ofThree Gorge Reservior region. Method By ways of the methods of alalogy,the methods of reviewed investigation and the imi-tative ecologic a l I e xpe r ime nt s. Res u l t and Coucl uslon It is m uch mo re confirmed t h a t t here a re not Oncomelania in Hubei partof Three Gorge Reservior region.
