摘　　要：目的探讨三峡库区洪水外包线内钉螺孳生环境形成的可能性。方法采用类比法、生态实验和现场调查 ,并利用三峡水库论证期间得到国家认可的洪水预测资料 ,取其血吸虫病研究可利用的部分 ,对洪水外包线内区域钉螺适宜孳生环境的形成进行了探讨。结果洪水外包线内存在大面积临时淹没区 ,其中主要危险环境有三类 :海拔 1 75m以上的洲滩边滩环境、支流开阔河谷环境和库周凹陷台地。观察表明 ,这些地方的土壤、植被、耕种利用和生态特征与钉螺孳生环境非常相似。结论钉螺在这些环境孳生的可能性极大 ,是库区将形成的主要的潜在钉螺适宜孳生地 ,且环境范围较大 ,应加强监测 ,以防止钉螺在库区孳生、蔓延 ,防止血吸虫病的传播流行。Aim To explore the possibility of development of snail habitat in Three Gorges Reservoir area Methods Analogy, ecological experiment and field investigation were applied Besides, flood forecast data authenticated by the state department concerned were also cited Results In Three Gorges Reservoir area inundated temporarily by flood, there are 3 types of dangerous environment i e islet or sandbank with an elevation above 175 m, wide valley of tributary, and the sunken table-land around the reservoir The results indicate that the type of soil, vegitation, cultivation and ecological chracteristics are similar to those of snail habitat greatly Conclusion There is always a possibility that potential snail habitat in these dangerous areas would be developed,so activities on snail surveillance should be strengthened
