目的：调查上海市医学贝类物种多样性及其分布。方法于2012年8月至2013年10月，根据水系分布特点，对上海市嘉定、青浦、宝山、闵行、松江、金山、崇明岛和浦东新区等8个区（县）各类生境进行现场抽样调查，采集医学贝类标本。所获标本经形态学鉴定分类，并对物种组成、生境及区系分布等进行分析。结果共获得标本5211只，经鉴定隶属于2纲14科18属，共计25种，包括湖北钉螺指名亚种、小管福寿螺、纹沼螺、长角涵螺、尖膀胱螺、小土蜗和尖口圆扁螺等。崇明、金山、浦东和青浦等区（县）物种相对较多，分别为22、22、21种和20种。生境分析显示河流和沼泽地物种分布最多，均为14种。区系分析表明上海市医学贝类以广布种和东洋界种类为主。结论上海市淡水腹足类物种相对匮乏，但多可作为中间宿主传播相关寄生虫病，应加强监测工作。

Objective To investigate the species diversity and distribution of medical mollusca in Shanghai City. Methods From August 2012 to October 2013,all kinds of habitats in 8 districts and counties in Shanghai City,namely Jiading,Qingpu, Baoshan,Minhang,Songjiang,Jinshan,Chongming,Pudong,were selected for the field survey according to the distribution characteristics of the river system,and all the specimens of medical mollusca in the investigation sites were collected and classi?fied by morphological identification. Meanwhile,the species composition,habitats as well as the fauna of the medical mollusca collected were analyzed. Results A total of 5 211 specimens were collected,which belonged to 2 classes,14 families,18 gen?era and 25 species,including Oncomelania hupensis hupensis,Pomacea canaliculata,Parafossarulus striatulus,Alocinma longicornis,Physa acuta,Galba pervia,Hippeutis cantori,etc. The species numbers of medical mollusca in Chongming,Jin?shan,Pudong new area and Qingpu districts(counties)were 22,22,21 and 20,respectively,which were more than those of other areas. The habitat analysis suggested that the species numbers in the river and wetland were the most,both of which were 14 species. The main faunas of the medical mollusca in Shanghai were the cosmopolitan and oriental species. Conclusions The freshwater gastropod species are paucity in Shanghai City,but almost of them can be served as the intermediate hosts of certain parasites to transmit snail?related parasitic diseases,so the surveillance of medical mollusca should be strengthened.
