摘　　要：目的调查2011年湖南省垸外血吸虫病易感环境分布现状及其特点,为制订综合防治措施提供科学依据。方法对湖南省垸外有人畜活动、历史上有钉螺分布及可能有钉螺分布的环境普查;收集垸外血吸虫病易感环境信息,采用GPS定位并建立空间数据库,应用Google Earth平台绘制垸外血吸虫病易感环境分布电子示意图,分析全省垸外血吸虫病易感环境分布现状及特点。结果2011年湖南省共有垸外血吸虫病易感环境洲滩787块,长1 429.64 km,面积62 017.17hm2,活螺平均密度为0.37只/0.1 m2,感染性钉螺平均密度为0.001 9只/0.1 m2,查出有感染性钉螺洲滩180块,感染性钉螺面积688.07 hm2;湘、资、沅、澧等16条有螺水系均有血吸虫病易感环境分布;垸外血吸虫病易感环境植被主要为杂草,其次为芦苇和树。结论湖南省垸外血吸虫病易感环境分布广、面积大、环境复杂,需进一步加强综合治理。Objective To investigate the current distribution of susceptible areas of schistosomiasis outside embankment, so as to provide the evidence for making comprehensive measures in HuMan Province. Methods The outside embankment areas where Oncomelania snails possibly or historically distributed and people and animals had activities were surveyed. The schistosomi- asis information of the susceptible areas was collected, a database was set up, the positions were marked with GPS, an E-map was drawn with Google Earth, and the distribution was analyzed. Result The number of marshlands with schistosomiasis susceptible areas outside embankment was 787, the length was 1 429.64 km, and the area was 6 2017.17 hm2. The average density of living snails was 0.37 snails/0.1 m2, and the average density of infected snails was 0.001 9snails/0.1 m2. The infected snails were found in 180 marshlands, and the area was 688.07 hm2. Sixteen rivers had the susceptible areas, and the main vegetation was weeds. Conclusions The susceptible area of schistosomiasis outside embankment is wide and complex. Therefore, the comprehensive con- trol measures should be strengthened.
