摘　　要：海水养殖除了保障人们的粮食安全外,在降低大气中二氧化碳的含量、缓解全球性的气候变暖方面也发挥着重要的作用。论文运用物质量评估方法对我国2007-2012年海水养殖贝类的碳汇量进行测算,其结果表明我国海水养殖贝类的碳汇能力是巨大的;在此基础上运用修正的Laspeyres指数分解法对影响碳汇量的因素进行了分析,结果表明产量因素对贝类碳汇量的作用要远远大于结构因素的作用,牡蛎、蛤对贝类碳汇的贡献较大,贻贝的贡献最小。In addition to safeguard people＇s food security, mariculture plays an important role in reducing the content of carbon dioxide in the atmosphere and alleviating the global warming. This paper measures the total amount of the carbon sink of seawater cultured shellfish from 2007 to 2012 in China using quality assessment methods, and the results find that the carbon sink capacity of seawater cultured shellfish is huge. On this basis, the reasons of the differences in carbon sink quantities are studied by using the modified Laspeyres index decomposition method, and the results find that the production factor plays a more important role on carbon sink amount increase than the structure factor; oysters and clams make relatively larger contribution to the shellfish carbon sinks, and the contribution of mussels is minimal.
