摘 要：本文就桃花岛潮间带进行贝类的实地采样调查，经过数据的整理、分析，初步确定桃花岛潮间带贝类的种类组成和数量，贝类的分布情况。调查采样分2次，分别是4月和11月。经调查，共采得贝类30种，分为3纲22科，主要为腹足纲和瓣鳃纲。根据数据处理，得出中潮带的生物量和栖息密度都高于高潮带的垂直分布规律；而在水平分布上，沙岙码头高潮带的2个数据都高于塔湾，中潮带则相反；通过4月和11月的数据对比，春季的数值高于秋季。 关键词：桃花岛；潮间带；贝类；生态学
Abstract:This article describes the Taohua Island, the intertidal zone shellfish field sampling survey conducted after the data collation, analysis, preliminary Taohua Island, the intertidal zone to determine the species composition and quantity of shellfish, shellfish distribution. Surveys sampling 2 times, respectively in April and November. After investigation,30 species of shellfish were collected,and was divided into 3 classes, 22 families, mainly Gastropoda and Lamellibranchina. According to the data processing, obtained that biomass and density in the middle tidal zone were higher than the high tidal zone; and on the horizontal distribution, Sha’ao terminal with the two data are higher than the Tower Bay in the high tidal zone, the middle tidal zone on the contrarry; Through data comparing of April and November, the values in spring higher than in autumn.
