摘要: 目的 分析安徽省长江流域螺情变化趋势,为钉螺防控提供理论依据。方法收集1992~2012 年间安徽省长江流域活螺和感染性钉螺密度及钉螺感染率资料,观察其变化趋势,并分析影响螺情变化的相关因素。结果 山丘活螺密度总体上最高,并于1993、1996、2001 年出现高峰期;1992~1998年江滩活螺密度高于洲滩,1998 年之后洲滩高于江滩,江滩活螺密度于1996、1998 年出现高峰期,洲滩于2003 年出现高峰期。洲滩感染性钉螺密度及钉螺感染率高于江滩、山丘,并于2004 年出现高峰期, 山丘于1993、1997 年出现高峰期。结论 长江流域螺情变化受自然和社会环境等多方面因素影响,在加强传染源控制的同时应重视螺情控制。

Abstract:

Objective To understand the trend of Oncomelania hupensis status in Yangtze River valley, Anhui Province, and provide basis for snail control. Methods The data of snail condition in the Yangtze River valley from 1992 to 2012 in Anhui province, including the density of living snails and infected snails, infected rate of snails was collected. The change trend and influence factors were analyzed. Results The density of living snails in hilly areas was generally higher than that in marshland, and 3 peaks appeared in 1993, 1996 and 2001. From 1992 to 2008 the density of living snails in the beach along the Yangtze River was higher than that in islets, and conversed after 1998. The density of living snails appeared 2 peaks in 1996 and 1998 in the beach and 1 peak appeared in 2003 in islets. The density of infected snails and the infected rate of snails in islets were higher than that in beaches and hilly areas. The density of infected snails and the infected rate of snails appeared 1 peak in islets in 2004 and 2 peaks in hilly areas in 1993 and 1997. Conclusion The situation of snails in the Yangtze River valley was related to natural and social circumstance, so we should strengthen both snail control and infectious source control.
