以我国海水养殖2005~2012年的数据为研究对象,运用物质量评估法对其碳汇能力进行了估算,结果发现我国海水养殖的碳汇能力巨大,年均碳汇能力达到100万t以上,且近年来呈现出增加的趋势。在此基础上,运用修正的Laspeyres指数分解法对我国海水养殖碳汇能力进行了分解研究,结果发现产量因素对海水养殖碳汇能力的变化起主要作用,结构因素的作用很小,最后提出了我国海水养殖业进一步增强碳汇能力的建议。
Based on the data of mariculture in China from 2005 to 2012, the carbon sequestration capacity of the mariculture in China was estimated using the method of material quality assessment. The results showed that the capacity of carbon sequestration in mariculture in China was huge, with an average annual carbon sequestration ability of over 1 million t. And has shown an increasing trend in recent years. On this basis, the modified Laspeyres index decomposition method was used to study the carbon sequestration ability of mariculture in China. The results showed that the yield factors played a major role in the changes of carbon sequestration ability in marine aquaculture, and the effect of structural factors was small. Finally, Proposals for China to further enhance its carbon sequestration capacity in mariculture industry.
