对东海中陆架泥质区及其周边的表层沉积物分别利用容量法、元素分析仪法进行了IC、OC含量分析，利用筛析法和沉降法进行了粒度分析。结果表明，研究区IC含量均明显高于OC含量。OC含量在泥质区高，砂质区低；IC含量分布为：近岸细粒沉积区为相对高值区，中陆架砂质区为低值区，中陆架泥质区为高值区，外陆架砂质区为特高值区。OC富集主要受控于上覆水体的生物生产量、沉积动力环境以及海底物理化学条件。IC的分布受物源影响明显，其富集与该区的环流格局相对应，主要受控于研究区的沉积动力环境和它们的时空变化。研究区的现代海底固碳能力可分为强固碳能力的中陆架泥质区、弱固碳能力的中陆架砂质区和基本无固碳能力的外陆架砂质区。
The contents of IC and OC in the sediments of the shelf and the surrounding sediments in the East China Sea were measured by the volumetric method and the elemental analysis method respectively. The grain size was analyzed by sieving method and sedimentation method. The results showed that the content of IC in the study area was significantly higher than that of OC. The content of OC is high in the shale area and low in the sandy area. The IC content distribution is that the fine sediment area in the nearshore is a relatively high value area, the sandy area in the middle shelf is a low value area, the shale area in the middle shelf is a high value area, The outer shelf of sandy areas for extra high value area. The enrichment of OC is mainly controlled by the biological production of the overlying water, the depositional dynamic environment and the physical and chemical conditions of the seafloor. The distribution of IC is obviously influenced by the provenance. Its enrichment corresponds to the circulation pattern in this area, which is mainly controlled by the depositional dynamic environment and their temporal and spatial variations in the study area. The seabed carbon sequestration capability in the study area can be divided into the mid-shelf muddy area with strong carbon sequestration ability, the mid-shelf sandy area with weak carbon sequestration capacity, and the sandy area with the outer shelf without carbon fixation.
