| Abstract: | Wetlands play a key role in regional and global environments and are critically linked to many major issues such as climate change,water quality,hydrological and carbon cycles,and wildlife habitat and biodiversity.Mapping wetlands and monitoring their change constitute a long-term task.Remote Sensing characteristics with macrocosm,dynamics,quantity,and comparability will largely favor wetland research.The radar remote sensing,which is not affected by climate conditions,has been especially proved to be an ef... |
