The aim of this study is to compare and analyze plant monitoring results of 2012 and 2013 for three artificial wetlands of
Binae, Sedo, and Okpo areas in Namhan river, Keum river, and Nakdong river respectively. As the results, the Binae wetland
in 2013 shows the same environment with 2012, that is, Willow and Common reed were dominant and the distributed plants
in the wetland were Phragmites japonica Steud, Carex dispalta Boott, and Humulus japonicus in lowland of river side. Especially,
Humulus japonicus was increased in summer season and Willow was increased in lowland of 초원. In Okpo wetland, Water
chestnut was appeared in 2013 which it was not in 2012. Reed distribution was reduced in 2013 comparing to 2012 but Pussy
willow distribution was not changed in 2013. In Sedo wetland, Secondary grassland was artificially planted in 2013 and so
the colony was changed to Chinese Lespedeza and also most of plant colony was changed to Colt's-tail. Therefore, we can
know that wetted transition rather than dried transition will be occurred in the Binae wetland. However, the Okpo wetland
has monotonic change and so the transition will be proceeded with long time. The Sedo wetland showed wetted and dried
transitions exist together. Therefore, the wetland will be changed to Reeds, Common reed, and Willow colonies.
