摘要
目的：了解长江安徽段新生洲滩的形成与钉螺滋生的关系。方法：调查滩地演变过程；采用纵横系统抽样法，结合环境随机抽样法查螺。结果：皖江段新生洲滩形成后，近年来由于人工开发滩地的干预，滩地植被生长与覆盖逐渐加速。滩地钉螺的出现在滩地植被覆盖后１０年左右；滩地钉螺的分布与植被分布基本一致。结论：新生洲滩一旦出现钉螺，即可向整个洲滩适宜钉螺滋生的范围扩散，随着人畜的介入。
The research to Chen Qiao beach of He county and Gong He beach of Wang Jiang county showed that snails on the beaches were almost identical with vegetation on beaches.About 10 years after vegetations grew up into beaches,the snails began to appear on the beaches and spreaded to all beaches.Now the vegetations grow up quickly because people develop wasteland,and there fore snails spread quickly.
