摘　　要：本文分析了大亚湾潮间带生物数量与分布特点，结查表明，其平均生物量为７３２．８５９／ｍ~２，平均栖息密度为 １２３９个／ｍ~２，生物量以藻类居第一位，栖息密度以软体动物居首位。岩石、沙滩和红树林泥滩生态相数量比较，生物量以岩石相最高，栖息密度以沙滩最高。数量垂直分布，生物量和栖息密度均为低潮区＞中潮区＞高潮区。The characteristics of quantitation and distribution of intertidal benthos, Daya Bay are analysed in this paper. The average biomass and density were 732. 85g/m^2 and 1 239md. /m^2 respectively. The algae was the first in biomass,while molluscswas the first in density. The biomass of macrobenthos in rocky habitat was the hightst,and those in the sandy shore was the first in density among three ecological habitat,rocky,sandy shore and muddy-mangrove shore. The biomass and density were higher in low tidal zone than middle,and more in middle than low in the vertical distribution of the quantity. The comparison of seasonal quantitati vevariation reveal that biomass washigher in winter than in falland the density washig herinw in ter than infall.
