摘要

Scientifically evaluating ecological restoration effectiveness based on vegetation-soil coevolution is crucial for ensuring stable improvement of estuary wetland ecosystems. Restoration effectiveness equations were developed for salt marsh environment, soil carbon and nitrogen environment, plant community structure, and plant community functional traits. The results show that the structure and functional traits of the soil habitat exhibit significantly better restoration trends after ecological restoration measures are implemented. Post restoration, the plant community structure was gradually restored to the level in undamaged areas, the plant biomass increased by a factor of 329 times, the carbon content increased by a factor of 1.32, and the soil salinity and organic carbon content were effectively regulated. In addition, the restoration effectiveness of the soil water–salt environment can cumulatively account for 81% of the restoration effectiveness of plant community functional trait. This study reveals the coevolution characteristics of two major carbon pools, that is, soil and vegetation, in estuary blue carbon ecosystems in the initial stage of recovery.
