Spatial Distribution of Vegetation on Stream Bars and the Riparian Zone Reflects Successional Pattern Due to Fluid Dynamics of River

The river is a dynamic space where erosion, transportation, and sedimentation are constantly occurring due to running water. This study aims reveal the change in geomorphology caused by flow characteristics of water rivers response vegetation that. was carried out clarifying spatially appearing successional trends established stream bars riparian zones, which located on different topographic conditions based profile, ordination result, species diversity. spatial distribution tended appear order annual plant-, perennial tree-dominated stands from upstream toward downstream direction (a gravel bar sand mountain gravel-bed an estuary, respectively) or reversed one lowland river). zones waterfront bank direction. Changes composition also differed depending location, showing similar trend vegetation. Species diversity became higher proportion longevity dominant each type. In conclusion, longitudinal pattern resembles lateral vegetation, follow pattern. These results suggest that dynamics bed loading, allogenic process, may be important determinant succession plant communities riverine environments.
