摘　　要：本文报道了厦门岛岩相潮间带生物276种，其中藻类、软体动物和其他动物占总数的65．21％。夏季和冬季平均生物量为1365．09g／m2，平均栖息密度为3110个／m2。生物量以甲壳动物居首位，软体动物居第二位；栖息密度以软体动物居首位，甲壳动物占第二位。All of 276 species of intertidal rocky benthos, Xiamen Island are reported in this paper.Algae, Molluscs and the others comprised 65. 21 % of all species. The average biomass and density were 1365.09g/m2 and 3100 ind. /m2,respectively in summer and winter. The Crustaceans was the first in the biomass, Molluscs the second; but the molluscs was the first in density, the Crustaceans the second. The horizontal distribution of the quantity, semi-sheltered transection had larger quantity than sheltered transection, and the sheltered larger biomass than the exposed;but the exposed transection was mors than semi-sheltered transection, and semi-sheltered was more than sheltered in density. In the vertical distribution of quantity, the middle tidal zone has the largest, and the high tidal zone the smallest. The seasonal variation of the quantity was larger in summer than in winters.
