The purpose of this study is to investigate the fluvial landscape ecology including river morphology,
riparian vegetation, and water quality on the Jupo River in Jinhae province, Korea at four regions
during four seasons. A transversal and longitudinal sandbar in this river was absent. Bed materials
at upper regions were composed of boulders and gravel. Bed materials at low regions were
composed of sand, silt, and clay (50% >). The flora on the Jupo River was a total of 66 taxa,
including 28 families, 57 genera, 59 species, and 7 varieties. Naturalized plants were 20 species at
overall regions. Upper region of this river was considerable high richness in flora. Naturalized
plants were shown with the relative high individual density and the number of species in low region.
The portion of BOD and COD in the river increased exponentially along the upper-down gradient.
There is evidence for a relationship between the ecological distance and environmental variables.
