To investigation the type of riparian vegetation and distribution, I studied the three streams, which is located in central district of Korea (Anyang Stream, Gap Stream, Seom River) from March of 2007 to December of 2008. Five different vegetation types were classified exception naked and openwater region. Natural forest type includes forest vegetation like as Quercus acutissima community and riparian woodland like as Salix koreensis community. Long and wet type of grassland consists of Phragmites australis community and so on. Robinia pseudoacacia plantation was representative of Woodland afforestation type. Short and dry type of grassland includes Elymus annuus and Humulus japonicus community. Cultivation land type. On the natural streamside was mainly made of natural riparian vegetation type, but in the artificial streamside consists of short and dry type of grassland. Riparian vegetation correlated with revetment structure, stream terrace, and microtopographical diversity. It showed that the vegetation type was divided clearly in the natural or artificial streamside.
