| 摘要: |
| 于1986－1991年在南海北部对16个海洋结构物上的无柄蔓足类水平分布、垂直分布和个体大小进行调查。研究表明，所采集到的标本隶属于无柄蔓足类的3科7属19种，其中藤壶科5属16种，笠藤壶科1属2种和小藤壶科1属1种。共有17种无柄蔓足类分布在珠江口东南海区；而琼东海区仅发现2种；琼东南海区有8种；莺歌海海区11种和北部湾海区10种。纵肋巨藤壶、美丽藤壶和珠江藤壶为珠江口东南海区特有种。研究无柄蔓足类在南海北部近海海区的分布及其与海流的关系，不仅有助于深入了解该类生物的生活习性和生态特点，也为海洋石油平台的设计及污损生物的防除提供参数。 |

| Abstract: |
| This paper deals with the horizontal and vertical distributions of Balanomorpha investigated on the submerged surfaces of 16 offshore structures (12 biological buoys, 3 Marex hydrological buoys, and a fixed oil production platform) in the northern part of the South China Sea during 1986 - 1991. Seven genera and 3 families were collected in these areas. Among the 19 species identified, 16 species, 5 genera belong to the family Balanidae, 2 species, 1 genus to Tetraclitidae, and 1 species, 1 genus to Chthamalidae. Except for Solid obalanur ciliazus and Chelonibia pazula, 17 species were collected in the southeast of the Zhujiang River Mouth. Megabalanus zebra, Balanus pulchellus and Balanur Zhujiangensis were not found in the areas out of the southeast of the Zhujiang River Mouth. Only 2 species were found in Qiongdong. Eight species were found in the Southern Qiongdong, 11 species in Yinggehai and 10 species in Beibu Bay. The source of Balanomorpha in the offshore areas and the influence of several factors, such as currents and the distance from shore, on their distributions are discussed. |
