| 摘要: |
| 分析了广东省南澎列岛3个主要岛礁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35科80种，以软体动物、甲壳类和藻类植物出现的种类最多，三者占总种类数的84％，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1 83131 g/m2，总平均栖息密度为21 867 ind/m2。各类群生物中，平均生物量以藻类居首位，栖息密度以软体动物居首位。其Shannon-Winer多样性指数(H′)属甚高水平，分布范围在3.32~3.57，平均为3.42；均匀度(J)为0.81～0.87，平均为0.84。 |

| Abstract: |
| The characteristics of species composition, quantity distribution and biodiversity of intertidal benthos in Nanpeng islands of Guangdong Province were analyzed in this study. Eighty species were found which belonged to 35 families. Mollusk, Crustacean and algae were the most abundant species, which comprised 84％ of the total species. and some of them were commercial species with high economic value. The average biomass and density of intertidal benthos in Nanpeng islands were 1，83131g/m2 and 21867 ind/m2, respectively. The algae and mollusks were the dominant species in biomass and density, respectively. The Shannon-Winer diversity index (H) was at high levels, distributing between a range of 3.32~3.57 with an average of 3.42; and its evenness (J) was between 0.81~0.87, with the average of 0.84. |
