As the impacts of climate change become increasingly pronounced, the role of ecosystems as sinks for atmospheric greenhouse gases has become increasingly important. In particular, wetlands have gained attention due to their high carbon storage capacity relative to their area. This study aimed to compare soil carbon storage and soil respiration between riverine wetlands and forest wetlands in Korea, and to identify key environmental factors influencing these processes. Seasonal surveys were conducted on the soil physical and chemical properties, carbon storage, and soil respiration in two riverine wetlands in the Geum River basin and one forest wetland in Goheung, Jeollanam-do. The analysis showed that the forest wetland stored 425.08±167.32 kg m-2 of carbon, approximately 26 times more than the 101.09±103.56 kg m-2 stored in riverine wetland soils. The forest wetland exhibited slow hydrological flow and low bulk density, creating conditions favorable for organic matter accumulation. Soil respiration measurements showed values of 0.31±0.28 gCO2 m-2 hr-1 in the riverine wetlands and 0.83±0.58 gCO2 m-2 hr-1 in the forest wetland, with no statistically significant difference between the two. Correlation analysis revealed a significant positive relationship with soil temperature (p<0.05) in both wetland types, indicating that temperature is an important factor regulating soil respiration. Additionally, total phosphorus was identified as a key factor in riverine wetlands, whereas pH was a major influencing factor in the forest wetland.
