Carbon storage or sequestration is important in studying its global carbon cycle and budget. To study annually carbon sequestration, sampling was carried out across three type plants and between depths on 8 soil profiles in the dry season (May, 2007), where lies in the newly creative salt marsh wetlands form Jianlin to Hekou rural area of the Yellow River Delta. The dating mark——paleosol for the calculation of sediment accretion rate was observed and identified in the field profile based on the sedimentary discontinuity as a result of frequently river course shifting.The lab analyses were focused on organic carbon, total carbon, nutrients and water contents. The wetland sediments were found to contain remarkable low in total and organic carbons (＜2% for TC, ＜1% for Corg), the C: N ratios of the soil were 50~53，and far from the stabilized soil of 15~25. The accretion rates of total carbon and organic carbon are 594~1771g/(m2·a) and 58～228g/(m2·a) respectively, which are comparable to those of the high carbon content marshes due to high sediment accumulation rate. Remarkably, the former was significantly related to sediment and total nutrients accumulation rates, while the later revealed positive correlation with organic carbon contents and other nutrients(Mn,Cu,Zn,Fe and so on). The nutrient contents of the soil were considered as the end members of wetland succession.
