摘　　要：于2008年7月15日至21日对洱海周边水域钉螺分布情况的调查发现,洱海东岸的3个镇(海东、挖色和双廊)所属水域均有钉螺分布;洱海南岸水域未发现钉螺分布;洱海西海岸水域除了仁里邑、作邑、州体育馆和才村码头外,其它地方均有钉螺分布;洱海北岸的上关镇水域钉螺分布范围最广,平均密度最大。对照相关资料,钉螺在大理地区分布范围已成扩大趋势。建议应对上关镇和洱海东岸水域着重治理,迅速予以消灭,同时对其它有钉螺分布的地方亦不能忽视。In order to get detailed data on the distribution pattern of Oncomelania hupensis in the Erhai region, a survey was conducted between July 15th and 21st, 2008. The results of the survey show that Oncomelania hupensis exists in most of the Erhai region except Manjiang, Renliyi, Zuoyi, Dali Gymnasium, Erhai Park and Caicun Duck. The density of Oncomelania hupensis is higher in the east of the Erhai region especially at Shanguan. The distribution pattern is opposite to the result in 1989. The efforts made to clear out Oncomelania hupensis should be strengthened especially in the east of the Erhai region.
