Abstract: The hydrological process plays an extremely important role in wetland formation,development,evolution and disappearance.Although many hydrological models on precipitation interception,streamflow and evapotranspiration have been developed,they need to be verified and improved.Sheet flow is difficult to model and calculate due to many factors affecting it.Furthermore,the groundwater system of wetland is especially important for seasonally flooded wetlands.The vertical hydraulic linkage in peatland is still uncertain.In addition,human activities and climate changes must be brought into integrated hydrological models for sustainable wetlands management.So far,there are only few integrated wetland hydrological models.The main study direction in wetland hydrology is to reinforce wetland hydrological monitoring,combine multiple approaches and modern technologies and develop integrated wetland hydrological models.
