摘　　要：深圳湾位于珠江口东岸,属半封闭海湾,2006年12月至2007年11月,在湾内进行污损生物周年挂板试验,共记录污损生物24种,隶属于7个动物门。月板平均附着生物量表层2780.72g/m2,底层4110.10g/m2,最高峰出现在7月份;四季板平均湿重表层2521.13g/m2,底层4382.10g/m2,最高峰出现在秋季;半年板平均湿重表层4065.10g/m2,底层4298.30g/m2;年板平均湿重表层6212.20g/m2,底层20009.10g/m2。四季优势种显著不同,华美盘管虫、总合草苔虫和藤壶在春、冬季附着量较大,夏季没有附着。沙筛贝和总状真枝螅在夏、秋季的附着量较大,冬季没有附着。Shenzhen Bay,located in the east of Pearl River estuary,is a semi-closed bay.From December 2006 to November 2007,an investigation with exposed test panels on marine fouling organisms was carried out in Shenzhen Bay.7 Phyla,24 species of fouling organisms were collected in the study.The monthly average biomass of fouling organisms was 2 780.72 g/m^2 on test panels of the surface layer and 4 110.10 g/m^2 on test panels of the bottom layer,and the highest amount appeared in July.The seasonal average biomass of fouling organisms was 2 521.13 g/m^2 on test panels of the surface layer and 4 382.10 g/m^2 on test panels of the bottom layer,and the highest amount appeared in autumn.The half-yearly average biomass of fouling organisms was 4 065.10 g/m^2 on test panels of the surface layer and 4 298.30 g/m^2 on test panels of the bottom layer.The yearly average biomass of fouling organisms was 6 212.20 g/m^2 on test panels of the surface layer and 20 009.10 g/m^2 on test panels of the bottom layer.Dominant species were different in four searsons.The biomasses of Hyfdddroides elegans,Bugula neritina and balanus sp.were larger in spring and winter,and they didn＇t grow on the panels in summer.The biomasses of Mytilopsis sallei and Eudendrium racemosum were larger in summer and autumn,and they didn＇t grow on the panels in winter.
