摘要
气候变暖威胁人类的生存与发展,减少CO2等温室气体的排放,发展低碳经济,缓解全球气候变暖的低碳经济是人类的共识。滤食性鱼类通过滤食浮游生物,间接降低大气中的CO2浓度而发挥碳汇作用。本文描述了一个不投饵的淡水生态系统的碳循环,探讨了滤食性鱼类在淡水生态系统中的碳汇作用,依据2009年全国水产养殖相关统计数据,估算了全国滤食性鱼类养殖的年碳汇量,为淡水渔业的低碳发展提供新思路,以推进现代化渔业的科学健康发展。
Climate warming has been a world-concerned global problem.It brings a series of serious consequences,greatly impacts human survival and development.To reduce carbon dioxide emissions and mitigate global warming,the development of the low carbon economy based on low energy consumption,low pollution and low emission has been our common sense.Fixing and sequestrating greenhouse gases by biological carbon sink is one of the most economical and effective ways.By filtering plankton,filter-feeding fish can reduce indirectly atmospheric carbon dioxide concentration and exert carbon sink function.The paper described carbon cycle of freshwater ecosystem without feeding,and presented carbon sink function of filter-feeding fish.At last,carbon sink amount of filter-feeding fish is evaluated based on 2009 relevant statistics of Chinese aquaculture.The research will make a good preparation for low carbon development of freshwater fisheries,and impel the scientific and healthy development of modern fisheries.
