海南分界洲岛潮间带至潮下带底栖贝类调查

摘要

Based on the investigation on shel fish resources from the intertidal zone to subtidal zone of Fenjiezhou Island, Hainan during 2012-2014, the quantity, species, ecological distribution and floristic characters of shel fish from the intertidal zone to subtidal zone of Fenjiezhou Island were analyzed. The results showed that a total of 137 shel fish species were found in Fenjiezhou Island, and they belonged to 4 classes [Polyplacophora (1 species), Gastropoda (94 species), Bivalvia (40 species), Cephalopoda (2 species)], 13 orders and 44 families. Among the families, Cypraeidae included 11 species, Muricacea included 9 species, Veneracea included 9 species, Conidae included 8 species, Strombidae included 6 species, Cymati dae included 6 species, and the other families al included less than 5 species. Accord-ing to the characteristics of the components, most of the species belonged to the tropical or subtropical region, and they had a close relationship with coral reef. Ac-cording to the floristic characters, the shel fish in Fenjiezhou Island belonged to the Indonesia-Malayan Subregion of Indo-West Pacific Region.%在2012～2014年期间，对海南分界洲岛潮间带至潮下带的贝类资源进行了调查，分析了该海域贝类种类与数量、生态分布、区系性质。结果表明，在分界洲岛共采集到贝类137种，隶属于4纲13目44科，其中多板纲1种，腹足纲94种，双壳纲40种，头足纲2种。各科的组成中，宝贝科11种，骨螺科9种，帘蛤科9种，芋螺科8种，凤螺科6种，嵌线螺科6种，其他各科的种类均小于5种。按种的性质而论，分界洲岛贝类大多数属于和珊瑚礁有密切关系的热带种或亚热带种，其区系性质属于印度-西太平洋的印尼-马来亚区。
