鄱阳湖水位变化影响下的血吸虫病传播

摘要院目的探讨鄱阳湖水位变化对鄱阳湖湖区湖北钉螺分布情况的影响；方法收集鄱阳湖湖区湖北钉螺数量变化资料与水位资料并进行统计分析；结果鄱阳湖平水年10月底湖水开始退干，至来年5月才开始淹水。4耀5月湖北钉螺产卵最盛时洲滩未被水淹，利于雌螺产卵，6月初紧接着水淹，又有利于螺卵孵化与幼螺的发育成长。水淹天数与显露天数直接影响着鄱阳湖湖区钉螺生态环节中产卵、螺卵孵化、幼螺发育成长，是影响湖北钉螺分布的重要因素。

• 关键词: Abstract Objective To explore the relationship between the snail distribution in marshland and the change of water level in PoyangLake region Methods The data of snails and water level which had been collected from Poyang Lake region were analyzed statistically Results At the end of October in every year，Poyang Lake begins to lose its water. The lake does not fill up with water from the five rivers until the next May. Female snails produce eggs in March to April baby snails hatch out from eggs in April to May and the number of snailsreaches peak in June. Waterlogged days and exposure days affect snail eggs hatching and growth of young snails and they are the importantfactors affecting the distribution of oncomelania hupensis.院鄱阳湖 水位 湖北钉螺Key words Poyang Lake water level oncomelania hupensis中图分类号院R184.1 文献标识码院A 文章编号院1006-4311（2014）27-0315-02
