Salinity stress is one of the critical environmental drivers soil organic matter (SOM) decomposition in coastal ecosystems. Although temperature sensitivity (Q10) SOM has been widely applied Earth system models to forecast carbon processes, impact salinity on by restructuring microbial communities remains uncovered. Here, we conducted a microcosm experiment with soils collected from salt marsh Yellow River Estuary, which subjected strong dynamics due both tidal flooding and drainage. By setting gradient solutions, was adjusted simulate emission (CO2) rate measured over period. Results showed that as increased, estimated constants based first-order kinetics gradually decreased at different temperatures. Below 20‰ treatments, doubled salinity, Q10 increased increasing salinity; but higher constrained temperature-related response inhibiting growth metabolisms. Soil bacteria were more sensitive than fungi, can be inferred beta-diversity changing salinity. Among them, phylotypes assigned Gammaproteobacteria Bacilli tolerance, whereas taxa affiliated Alphaproteobacteria Bacteroidota easily inhibited stress. Several fungal belonging Ascomycota had adaptability As substrate consumed incubation, bacterial competition intensified, co-occurrence pattern changed weakly during decomposition. Collectively, these findings revealed threshold effect marshes emphasized plays key role sequestration regulating keystone taxa, metabolisms, interactions.
