Abstract

Abstract:

In this study, in-situ simulated control experiments were conducted to investigate the effects of straw burial on vegetation recovery and carbon sequestration function of eutrophic salt marshes, by monitoring plant growth traits, photosynthetic characteristics, and greenhouse gas fluxes, as well as the soil organic carbon density measured at the end of the experiment. The results revealed that under a high exogenous nitrogen input, straw burial was beneficial for the growth of Phragmites australis and carbon sequestration of wetland, specifically by promoting CO₂ uptake, inhibiting CH₄ emissions, and increasing soil organic carbon density. The findings of this study aim to address the current lack of understanding regarding the carbon sequestration potential of salt marsh ecosystems. Through investigating the utilization of salt marsh straw, this study can provide technical support for vegetation restoration and carbon sequestration in the coastal wetlands, and may help promote the utilization of salt marsh straw.

Key words: salt marsh wetland, Phragmites australis, straw burial, carbon sequestration, eutrophication
