摘　　要：血吸虫病是一种严重危害人民健康、影响社会经济发展的传染性疾病,钉螺是血吸虫的唯一中间宿主。1998年洪水后实施的"平垸行洪、退田还湖"措施对于钉螺和血吸虫病的扩散有着重要的影响。总结影响钉螺和血吸虫病扩散的因素,并对典型"平垸行洪、退田还湖"后钉螺和血吸虫病变化情况进行调查研究,结果表明,认识某一区域钉螺和血吸虫病扩散规律需要综合考虑自然环境、人类活动以及二者之间相互作用。由于"平垸行洪、退田还湖"实施方式不同,实施后钉螺和血吸虫病扩散变化情况存在着很大差异。同时,针对不同的实施方式和血吸虫病变化情况,提出了控制钉螺和血吸虫病扩散的对策和措施。Schistosomiasis is a water-bourne parasitic disease endemic to Yangtze River basin of China.And the disease epidemic would be seriously influence on the public health and socio-economic developing.After the big flood of 1998,a lot of flood control measures such as ＂discharge of flood by removing some of dikes,giving up the cultivated land around for restoreing of lake＇s capacity＂ were brought into effect.However,the flood control measures would be extensive in influence on the river ecosystem,and also the Oncomelania snail and Schistosomiasis transmission dynamics was affected by the flood control measures.In this article,the factor that affected transmission dynamics of Oncomelania snail and schistosomiasis was summarized,and the change of Schistosomiasis epidemic after flood control measures implemented was investigated.The results show that： transmission dynamics of Oncomelania snail and schistosomiasis is relation to the nature habitats and human activity,and also relation to the results of interaction between nature habitats and human activity.In the areas where the flood control measures implemented,the transmission dynamics of schistosomiasis present different results because of the different way of the measures implemented.And in this paper the measures controlling epidemic of schistosomiasis were brought forward against the different flood storage and detention areas.
