Abstract: Wetland, located in the terrestrial aquatic transverse zone, is an important landscape and ecosystemWetlands 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 structuresBut over past decades, wetland landscapes have been changed greatly, and these changes have relationship with land use / cover changes as well as human activitiesWetland landscape changes in structure and process have huge impacts on environmental changes caused by the spatial and temporal interaction of wetland natural ecosystem processesUp to now, a natural wetland pattern has been changed to a human dominated land use pattern by human beingsThe 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 atmosphereWetland 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
