摘　　要：1986年6月至1987年6月，在北部湾东北部离岸分别为40和3．6nmile处布设了BZ，B3两个浮标调查站，以了解该海区的污着生物生态特点。调查结果表明，该水域的污着生物主要为热带、亚热带海域沿岸常见种类，其中无柄蔓足类在近岸的B3站处于绝对优势的地位；至于远岸的BZ站；不仅珍珠贝和牡蛎等双壳类软体动物的生物附着量（湿重）高于B3站，而且还有少量的茗荷Lepasanatifera、鹅茗荷L．anserdera等外海性种类出现。To understand the ecological characteristics of fouling communities inoffshore oil areas of the Beibu Gulf, the northern South China Sea, tWo experimentalbuoys(B2,B3) were deployed 40 and 3.6 n Anies off shore respectively within thePeriod from JUne 1986 to June 1987.The results showed that biofouling communitiesin mis waters were primarily composed of tropical and subtropical littoral species suchas acorn barnacles,oysters and Pearl oysters etC. As for open-sea species, only Lepasanatifera and L. anserifera were collected at Station B2 and the amount was small.The maximum accumulation of fouling was found at Station B3 where Balanusreticulatus was the most predominant species.With the increase of distance from shore,the proportion of biomass occupied by bivalve,particularly Ostridae and Pteriidae,increases.At the same bine, the substantial reduction of total biomass and a change inspecies compositions also occurred in the seaward direction. In addition,the source offouling organisms and several factors contributing to the distribution of sessile marinespecies were also discussed.
