摘要： 贝类作为海洋生态系统重要组成部分，通过生物活动利用和固定海水中CO2，发挥重要碳汇作用。本文基于碳储量法探究了烟台各海域不同种类、个体大小贝类的碳汇能力。结果表明，不同种贝类碳汇能力差别巨大，且随着个体增大其碳汇能力显著增强。其中长牡蛎、褶牡蛎、栉孔扇贝、海湾扇贝及贻贝的碳汇能力分别介于3.37~16.64g·a-1，2.87~14.17g·a-1，0.41~4.19g·a-1，3.16~1.73g·a-1及0.21~0.38g·a-1。牡蛎的碳汇能力远远高于扇贝和贻贝（P<0.01），且不同海域相同贝类的碳汇能力无显著差异（P>0.01）。此外，基于贝类碳汇计量指标的实际测定值与标准参考值进行烟台市养殖贝类碳汇量核算发现，牡蛎碳汇量实测值显著高于标准估算量（P<0.01），而扇贝的碳汇量实测值显著低于标准估算量（P<0.01），表明贝类碳汇与其种类及个体大小直接相关，反映了贝类碳汇核算方法的复杂性与重要性。

Abstract: Bivalves play an important role as carbon sinks by absorbing and fixing CO2 in seawater. This study explores the carbon sequestration capacity (CSC) of different species and sizes of bivalves by determining its carbon stocks in Yantai sea area. The results showed that the CSC of different species differed greatly, and increased significantly with individual size. The CSC of Crassostrea gigas, Ostrea plicatula, Chlamys farreri, Argopecten irradians and Mytilus galloprovincialis were 3.37~16.64g·a-1，2.87~14.17g·a-1，0.41~4.19g·a-1，3.16~1.73g·a-1and 0.21~0.38g·a-1, respectively. The CSC of oysters was much higher than that of scallops and mussels (P<0.01), and there was no significant difference among different sites. In addition, based on the measured and the standard reference value of parameters of bivalves carbon sink evaluation, the actual amount of oyster carbon sinks in the three areas was significantly higher than the estimation based on standards (P<0.01), and the opposite was true for scallops. There was no significant difference between the actual carbon sinks ofA. irradians and M. galloprovincialis in Changdao waters and the standard estimation (P<0.01), which was related to bivalve species and individual sizes, reflecting the complexity and importance of bivalve carbon sink accounting methods.
