摘　　要：报道了广西防城港港口区旅游海区玉石滩硬相潮间带的4种滨螺,包括粗糙滨螺Littorina scabra、波纹滨螺Littorina undulate、塔结节滨螺Nodilittorina pyramidalis pyramidalis和粒结节滨螺Nodilittorina millegrana,并对其中3种的数量、分布、周年变化、个体大小等方面进行研究。其中塔结节滨螺为潮上带的优势种,而粗糙滨螺为高潮带的优势种;分布于高潮带的滨螺个体明显较潮上带的大。Littorinidae in the rocky supratidal and intertidal zones of Yushitan, Fangchenggang, Guangxi was investigated. Four species, Littorina scabra , Littorina undulate, Nodilittorina pyrarnidalis pyrarnidalis and Nodilittorina millegrana, were identified, and three of them were studied quantitatively. N. pyrarnidalis pyrarnidalis was the dominant species in the supratidal zone and L. scabra was the dominant species in the upper intertidal zone. The size of Littorinidae in the upper intertidal zone was distinctly bigger than that in the supratidal zone.
