Investigation on Carbon Storage and Preliminary Research on Carbon Sink Potential of Mangrove in Nansha Wetland Park
Mangrove has high carbon sequestration and storage capabilities due to its potent photosynthetic capa-bility,which made it a crucial component of blue carbon in the coastal zone.In this study,mangrove in Nansha Wetland Park was chosen for investigation.By means of fixed sampling,community investigation,soil sample and litter sample collection,the carbon storage of mangrove vegetation,sediment and litter were investigated and stud-ied for two consecutive years.The alteration of carbon storage of the ecosystem was assessed,and the carbon sink potential of the ecosystem was initially explored.The results demonstrated that the total carbon storage of man-grove ecosystem in 2022 was 9453.53 MgC and the average carbon storage was 176.67 MgC/ha with the carbon storage of vegetation,sediment and litter accounting for 15.99％,82.02％and 1.99％respectively.In 2023,the to-tal carbon storage of mangrove ecosystem was 10190.38 MgC and the average carbon storage was 190.44MgC/ha with the carbon storage of vegetation,sediment and litter accounting for 20.78％,77.28％and 1.94％respectively.Compared with 2022,the carbon storage of the mangrove ecosystem in 2023 increased by 736.85 MgC with an in-crease of 7.79％,indicating that the mangrove ecosystem of the wetland park has a considerable carbon sink po-tential.
