摘 要:通过室内实验、数学模拟的方法研究了桑沟湾养殖栉孔扇贝通过呼吸、钙化等活动对湾内碳循环的影响,并与生物沉积碳相比较发现,养殖扇贝每年通过呼吸和钙化分别放出碳1.22×104t和7.57×102 t;但通过生物沉积作用每年有8.71×104 t碳被沉降到沉积物界面,这些碳绝大部分被埋藏从而脱离了地球化学循环。尽管养殖扇贝通过呼吸和钙化释放出部分碳,但有更多的碳通过生物沉积作用被埋置因此,从整体上看,养殖栉孔扇贝在湾内碳循环中参与了碳汇的作用。

Abstract: Impacts on carbon cycle of Chlamys farreri by respiration, calcification and biodeposition in Sanggou Bay was researched by the method of laboratory experiment and mathematical stimulating. These were 1.22×104t and 7.57×102t carbon releasing each year by respiration and calcification of Chlamys farreri respectively; and these was 8.71×104t carbon sinking to the bottom of sea by biodepositon, most of which would been buried and leaving geochemical circulation. Though carbon was releasing by respiration and calcification, more carbon was buried by biodepositon. So Chlamys farreri should be considerd as carbon sink as a whole.
