Distribution Characteristics of Soil Organic Carbon in Nandagang Mudflat Wetland
Coastal mudflat wetland is an important space resource to improve carbon sink and compensate carbon emission.In order to study the distribution characteristics of soil organic carbon in coastal mud-flat,sampling sites were set in Nandagang mudflat wetland in Hebei Province.The content of soil organic carbon under different wetland types and different vegetation cover were collected.The results showed that the average content of soil organic carbon in Nandagang mudflat wetland was 8.03±3.39 g/kg,which was slightly lower than the national average level.There were some differences in the spatial distri-bution of soil organic carbon.The contents of soil organic carbon in inland mudflat wetland were higher than that in coastal mudflat wetland.The content of soil organic carbon decreased with the increase of soil depth,and the contents of soil organic carbon were significantly different at different depths.The contents of soil organic carbon were different under different plant communities,which showed that Phragmites au-stralis community>Cyperus rotundus community>Suaeda glauca community>Ceratophyllum demersum community>pure mudflat.The distribution of soil organic carbon density in Nandagang mudflat wetland was similar to that of soil carbon content.Soil structure and surface vegetation types had an impact on soil organic carbon content and carbon density distribution.
