Abstract: [1] Despite considerable research, large uncertainties exist in the various area-scales budgets of CH 4 flux between soils and the atmosphere. We postulated that small wetlands greatly contribute to the CH 4 budget in semiarid regions, where wetland contributions are often assumed to be insignificant. To test this hypothesis, small riparian mires of the Xilin River basin in Inner Mongolia were selected as a case study for weekly measurements of in situ CH 4 flux. Average CH 4 fluxes were 234.3 and À1.9 mg CH …
