通过浅海贝类和大型藻类的养殖,可以吸取水体中的碳,从而提高海水养殖的碳汇潜力.依据渔业部门的统计数据及前期研究成果,采用物质守恒定律,对我国海水养殖的贝类和藻类的碳汇作用进行了估算.以2007年我国贝藻养殖的CO2吸收量为基数,并根据我国2007—2013年的贝藻养殖产量的增长趋势,趋势外推得到2016—2025年的贝藻养殖产量.结果表明,2025年我国贝藻养殖可以吸收606.171万t CO2,经济价值相当于9.1亿~36.4亿美元.因此,海水养殖具有非常大的社会效益、生态效益和经济效益.
通過淺海貝類和大型藻類的養殖,可以吸取水體中的碳,從而提高海水養殖的碳彙潛力.依據漁業部門的統計數據及前期研究成果,採用物質守恆定律,對我國海水養殖的貝類和藻類的碳彙作用進行瞭估算.以2007年我國貝藻養殖的CO2吸收量為基數,併根據我國2007—2013年的貝藻養殖產量的增長趨勢,趨勢外推得到2016—2025年的貝藻養殖產量.結果錶明,2025年我國貝藻養殖可以吸收606.171萬t CO2,經濟價值相噹于9.1億~36.4億美元.因此,海水養殖具有非常大的社會效益、生態效益和經濟效益.

Through the shallow sea shellfish and macroalgae of mariculture,the carbon in the water was obtained,and the carbon sequestration potential of marine culture was improved. According to the statistical data of fishery department and the results of previous research,the carbon sink function of shellfish and algae in the sea water were estimated by the law of conservation of matter. As the base of CO2 absorption amount in 2007 with the shellfish algae,and according to the growth trend of the production of shellfish algae during 2007—2013 in China,trend extrapolation was employed to obtain the production of shellfish algae in 2016—2025.The results showed that the 6.061 71 million tons CO2 of shellfish culture could be absorbed in 2025,equivalent to the economic value of 0.91~3.64 billion dollars. Therefore,mariculture has very large social benefits,ecological benefits and economic benefits.
