摘要
分析了广东省闸坡潮间带生物的种类组成、数量分布和生物多样性等特点。结果表明,该海域潮间带调查采获的潮间带生物标本共55科80种,以软体动物和甲壳类出现的种类最多,两者占了总种类数的85%,其中部分属经济价值较高的种类。潮间带生物总平均生物量为7 420.92 g/m2,总平均栖息密度为3 929.93 ind/m2。全年各类群生物中,平均生物量及栖息密度都以软体动物居首位。其Shannon-Weaner多样性指数(H)属中等水平,分布范围在1.657～4.226,平均为2.848;均匀度(J′)为0.390～0.721,平均为0.612;种类丰度(D)为2.062～4.234,平均为2.964。
The characteristics of species composition,quantity distribution and biodiversity of inter-tidal benthos in Zhapo of Guangdong were analyzed in this paper.The results indicated that there were 80 species which belonged to 55 families,and species of Mollusk and Crustacean are the most which comprised 85% of all species,and some are the commercial species with high value.The average biomass and density were 7 420.92 g/m^2 and 3 929.93 ind/m^2,respectively.The mollusks were the first in biomass
