Abstract: Wetland, located in the terrestrial aquatic transverse zone, is an important landscape and ecosystemWetlands have huge environmental functions in maintaining ecological balance and regional stability due to their particular characteristics in hydrology, soil, and plant, as well as landscape ecological structuresBut over past decades, wetland landscapes have been changed greatly, and these changes have relationship with land use / cover changes as well as human activitiesWetland landscape changes in structure and process have huge impacts on environmental changes caused by the spatial and temporal interaction of wetland natural ecosystem processesUp to now, a natural wetland pattern has been changed to a human dominated land use pattern by human beingsThe processing of wetland changes influenced wetland and other ecosystem in biodiversity, primary productivity, and global biogeochemistry cycle, as well as greenhouse gas contents in the atmosphereWetland change also has clear impacts on climate change, hydrological change, biodiversity change in regional or global scales.
Key words: Cumulative effect, Landscape change, Wetland change process
