香港维多利亚港码头的附着生物群落

Biofouling communities on piers in Victoria Harbour

香港维多利港自东至西6座码头的附着生物群落较旺盛，物种多样性比较丰富（183种），其中还有一些外来物种．各湖区的群落结构差别很大．高潮区以滨螺（Littorinabrevicula等3种）-笠贝（Cellanatoreuma等）为标志；中潮区是笠藤壶（Tetraclitaspp．）-牡蛎（Saccostreaechinata）带；低潮区是翡翠贻贝-瘤海鞘-海绵和网纹藤壶带．流急、浪大是群落较旺盛发展主要因子．

The species diversity of biofouling communities is rather abundant on 6 piers from the east to west of Victoria Harhour (183 spp. ), and one foreign species was also found. The community structure is much different on each tidal zone. Littorinaand Cellana are dominant on high tidal zone, middle tidal zone is Tetrarlita Saccostrea zone and on low tidal zone are mainly foundPerna,Styela, Spongia and Balanus. Rapid currents and big waves are the main factors affecting the development of the communities.
