英文摘要	Sedimentation rate plays an important role in wetland deposition because it indicates the storage capacity of wetland sediment and biogenic element. In this study, two sediment columns with a depth of 50 cm were collected in the restored wetland in the Yellow River Delta, and 10 soil physical and chemical properties were measured. The change point of the soil properties and the age since wetland restoration were used to determine the sedimentation rate. The results showed that the variables such as TOC, TN, delta~(13)C, and delta~(15)N, which were related to the accumulation of soil organic matter, were more suitable for calculating the deposition depth of the new layer of sediment in the restored wetland. As a result, the average sedimentation rate of the new layer in R2002 was calculated as 0.75 cm·a~(-1), and the deposition rates of C, N, and P were 208.65 g·m~(-2)·a~(-1), 20.74 g·m~(-2)·a~(-1), and 4.11 g·m~(-2)·a~(-1), respectively. In conclusion, the change point technique can be accurately used to determine the sedimentation rate of the new layer in restored wetland. In the future, the restored wetland will play more and more important role in sequester excess nutrient (such as N or P) due to human activities and global climate change.
