Landscapes are spatially heterogeneous geographic areas characterized by diverse interacting patches. Each patch may host diverse aquatic and terrestrial fauna and flora within an ecosystem. Few studies of landscape ecology focused on the combination of terrestrial and aquatic areas. A riverscape model was developed for adopting river environmental plans especially for characterizing the spatial composition and configuration of habitat patches before and after installing hydraulic structures in the project. The non-tidal reaches of the Wu River and Nangang Creek, and tidal reaches of Tanshui River were selected as case studies.景觀生態河川環境規劃河相植生棲地烏溪南港溪淡水河landscape ecologyriverscapeFRAGSTATSriver hydrodynamicsriver morphology
