对上川岛潮间带软体动物进行了采集调查，共鉴定软体动物172种，分属46科．其中腹足纲25科82种，占总数的47．67％；双壳纲21科90种，占总数的52．33％．分析表明，其区系特点为南海亚热带-热带种和东海-南海亚热带种为主要成分．同历史资料比较，广温广布种明显减少，南海亚热带-热带种获得发展；部分有经济价值的种类已经消失；养殖造成滩涂软体动物物种单一性；外来速生种墨西哥湾扇贝的养殖对滩涂其他软体动物的生态威胁需要进行评估．

The molluscs in the intertidal zone of Shangchuan island were collected from 201 1-2013.A total of 172 species belonging to 46 families,were identified.Among them,82 species belong to 25 families of Gastropoda,90 species belong to 21 families of Bivalvia.The results show that the most advantageous species in fauna of mollusk on the intertidal zone of Shangchuan island are the tropical and subtropical warm water species distributed in the South China Sea,and the subtropical warm water species distributed in the East China Sea and the South China Sea.Some economic value species recorded in history data have disappeared.Due to the aquaculture,the unicity of mollusc species in mudflat appears.The ecological menace on other mollusks,caused by the cultivation of foreign fast-growing species,Argopecten irradians concentricus,should be evaluated.
