摘要
本文对福建南部(23°35′24″-24°23′45″N；117°13′40″-118°07′30″E)岩相潮间带的生态特点进行了分析。所调查3个断面中，主要优势种和习见种都为广分布种和亚热带暖水性种类，主要优势种有塔结节滨螺、棘刺牡蛎，复瓦小蛇螺、鼠尾藻、羊栖菜、珊瑚藻等。其生物分带现象列显，高潮带为滨螺带，中潮带为棘刺牡蛎带，低潮带为混合藻类带。3断面可分为开敞型和半封闭型二种环境类型，以半封闭型岩石岸种类丰富、生物量大。
The present paper deals with the result of the preliminary investigation on the ecology of the rocky of the intertidal zone, which stretches from the Jiulongjiang estuary to the kongkou harbour in the southern Fujian (23°35′24″—24°23′45″N; 117°13′40″—118°07′30″E). The fauna and flora of this region on rocky tidal zone are abundant. According to the samplings taken from three localities, a total number of 247 species were identified, of which 53 species belong to algae, 2 to Bryozoa, 2 to spongia, 7 to Coelenterate, 45 to Polychaete, 6 to Sipunculoidea, 95 to Molluscs, 25 to Crustacean and 10 to Echinodermata. Most of them are tropical and subtropical species and also eurythemic species. The vertical zonality of the species are distinct. On the high water zone, a littorina zone can be seen, on the middle water zone an ostrea-serpulorbis(or Tetractita) zone can be seen, and on the low water zone, several species of algae make an algae zone.The rocky tidal zone along the coast of Southern Fujian Province could be divided into two types, namely, open shore and closed shore. The species composition, the biomass, the dens-i ty, the community structure differ from each other. Both the species and the biomass of the closed shore are greater than those of the open shose.
