中文摘要：通过对长江外滩枫杨防护林和芦林钉螺分布密度的调查比较，结果表明：枫杨林钉螺分布密度明显低于芦林；两种群落钉螺分布密度不同程度受长江洪泛的影响；两种群落中4种抑制钉螺的植物对钉螺分布密度的影响相似。
英文摘要：The distribution density of Oncomelania hupensis has been investigated in Pterocarya stenoptera community and Phragmites communis community on beach of the Yangtze River. The results showed that the density of O. hupensis population was apparently lower in P. stenoptera community than in P. communis community. The distribution density in both communities was affected by the flood of the Yangtze River. The constrain effect of four plant species on O. hupensis population density in the both communities revealed similar.
