Abstract: Wetland is the outcome of the interaction between terrestrial and aquatic ecosystems under integrated effects of various ecological processes in different scales, and characterized by prominent spatial heterogeneity. As a main research means, landscape pattern analysis can help us understand the spatial ecological process. Wetland hydrology is the most important determinant of the establishment and maintenance of specific type of wetland, which has a direct effect on the biota in the wetland and makes some changes on landscape ecological pattern. Being a feedback to the wetland hydrological processes and their physical environments, wetland biota can control the hydrology and chemistry of the environments through a variety of mechanisms. The studies on the coupling between wetland ecological pattern and hydrological process would be the keystones in the future research on wetland ecosystem.
