This study was conducted from March to October 2003 to investigate the distribution status and environmental index of naturalized plants at 14 sites at rivers penetrating the downtown area of Gwangju Metropolitan City. The flora consisted of 309 taxa, 76 families, 211 genera, 273 species, 35 varieties and one form, while the naturalized plants consisted of 46 taxa, 14 families, 36 genera, 44 species and two varieties. The dominant species of Gwangju-cheon were nine taxa. Panicum dichotomiflorum, Rumex crispus, Chenopodium album, Trifolium repens, Veronica persica, Ambrosia artemisiifolia var. elatior, Aster pilosus, Bidens frondosa and Taraxacum offici-nale. The dominant species of Hwangryong River were five taxa: Rumex crispus, Trifolium repens, Oenothera odorata, Ambrosia artemisiifolia var. elatior and Erigeron canadensis. At Yeongsan River appeared 16 dominant species: Patspalum distichum, Ckenopodium ficifolium, Lepidium apetalum, Erigeron annuus and Xanthium strumarium in addition to the same dominant species of Gwangju-cheon and Hwangryong River The Urbanization Index (UI) was 17.2% and the Naturalized Index (NI) was 14.9% at urban rivers of Gwangju. The naturalized plants consisted of 16 taxa, which originated in both Europe and North America. Based upon the UI and NI, the urban rivers and their riversides must be considered a major corridor for the invasion of naturalized plants.
