Abstract: Wetland hydro-ecology is a key research field for ecologists, hydrologists and wetland investigators to quantify the relationship between wetland ecological patterns and hydrological mechanisms. Existence and functioning of wetlands is crucial for adjacent terrestrial and aquatic ecosystems. Hydro-ecological research promotes both protection and restoration of healthy natural wetlands by further understanding the biophysical characteristics of wetland habitats. This study establishes a wetland hydro-ecological model with the methodological support from geographic information system (GIS) and remote sensing (RS). It conceptualises a cause–effect chain interface from the real wetland ecosystem. GIS and computer modelling methods are used to generate the hydrological indicators based on a Digital Elevation Model (DEM). By interpreting multi-temporal RS images, we produce wetland classification information and various landscape indices. Both hydrological and landscape indicators are used to integrate the hydro-ecological analysis with some multidisciplinary analysis methods.
