Dissolved organic matter (DOM) is the predominant form of aqueous carbon export from wetland soils. However, in restored alpine wetlands, the hydrological control over DOM composition, specifically how restoration‐induced moisture changes differentially reshape fluorescent signatures in meadow versus peat wetlands, remains unresolved. Here, we collected 0–20 cm soil samples from two typical wetlands (meadow and peat wetlands) subjected to both grazing and restoration treatments (through micro‐dam construction) in the Zoige area. Dissolved organic carbon (DOC) concentrations and DOM fluorescent components were analyzed to explore whether restoration has a consistent impact on DOM. The results demonstrated that the DOC concentration in the meadow wetland was significantly ( p
