摘　　要：通过对莱州湾增殖型人工鱼礁附着生物的取样调查,分析了礁体附着优势种褶牡蛎壳干质量、总湿质量和附着厚度的季节变化及其随礁龄变化的差异,并对礁区的总固碳量进行了估算.结果表明：增殖礁礁体附着褶牡蛎壳干质量和总湿质量均呈现明显的季节性变化（P〈0.01）,4月最低,12月最高.增殖礁礁龄对附着褶牡蛎壳干质量、总湿质量和附着厚度影响显著（P〈0.01）,均随礁龄的增加呈递增趋势.莱州湾圆管型增殖礁5、4和3年礁龄的礁体附着牡蛎固碳量分别为17.61、16.33和10.45 kg·m-3.2009—2013年,莱州湾金城海域64.25 hm2海洋牧场圆管型增殖礁礁体上附着牡蛎总固碳量约为297.5 t C,相当于封存了1071 t CO2,而封存固定这些CO2所需费用约1.6×105-6.4×105美元.因此,增殖礁附着牡蛎具有巨大的生态效益。Through sampling investigation of fouling organisms on the enhancement artificial reefs set up in Laizhou Bay, it was proved that oyster （ Ostrea plicatula） was the dominant fouling species. Therefore the dry mass of shell （Ms）, total fresh mass （Mt） and thickness （T） of oyster attached on the reefs were analyzed. The results showed that the Mt and Ms presented seasonal variation （ P〈0.01 ）, that is, the values were the lowest in April and the highest in December. The reef age and the length of the time the enhancement reefs placed in the sea had significant effect on Mt, Ms and T. With the increment of reef ages, all indices increased obviously. The carbon sinks of oysters attaching to the tube enhancement reefs constructed in 2009, 2010 and 2011 in Laizhou Bay were 17.61, 16.33 and 10.45 kg · m-3, respectively. The oysters on the enhancement reefs of Jincheng marine ranch with an area of 64.25 hm2 had fixed carbon of 297.5 t C （ equivalent to 1071 t of CO2 ） from 2009 to 2013 in Laizhou Bay. To capture and store the same amount of CO2 would cost about 1.6 × 105 -6.4 × 105 US dollars. Therefore, oysters attaching to the enhancement reefs bring about remarkable ecological benefits.
