| 摘 要： | 分析了楚科奇海数个站位表层沉积物中有机碳含量、J8站位的沉积速率和有机碳含量的垂直分布.结果显示沉积物中有机碳含量为0.56%～2.00%,平均值为1.31%（m/m,下同）,J8站位有机碳含量随埋藏深度的增加呈略为降低的趋势,有机碳的埋藏速率约1.56mg/（cm2.a）,相对于楚科奇海和该站位的浮游植物光合作用合成的有机碳而言,进入沉积物的有机碳占初级生产力的比例很高.这说明楚科奇海沉积物有很高的接纳初级生产者产生的有机碳并将其固定、保存的能力.

| Abstract: | The content of organic carbon in the surface sediments of Chukchi Sea and the vertical distribution of organic carbon at Station J8 was investigated.The content of organic carbon was about 0.56%～2.00%,and the average value was 1.31%（m/m）.At Station J8 the content of organic carbon decreased with increasing depth,and its burial rates was about 1.56mg/（cm2·a）.Compared with the organic carbon photosynthesized by the phytoplankton at Chukchi Sea,the organic carbon entering the sediment had high ratio for the primary productivity.It shows that Chukchi Sea has very high capability to accept and fix up the organic carbon derived from primary productivity. |
