我国海水养殖业碳汇能力测度及其影响因素分解研究

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。

Research on China's mariculture carbon sink capacity and influencing factors

This paper measures the total amount of the carbon sink of mariculture from 2005 to 2012 in China using quality assessment methods,and the results find that the carbon sink capacity of mariculture is huge.The average capacity of the carbon sink of mariculture can reach 1 million tons per year,and the capacity of the carbon sink presents an increasing trend in recent years.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.Finally,this paper puts forward the suggestions for the improvement of China's mariculture carbon sink capacity.
