The present study was undertaken to classify and describe the riparian vegetation of the 6 river·stream of Korea Peninsula. As a result the vegetation was divided into nineteen communities. The vegetation units obtained in the present study were as follow: A: Salix koreensis community, B: Salix gracilistyla community, C: Robinia pseudo-acacia community, D: Amorpha fluticosa community, E: Brousonnetia papyrifera community, F: Phyllostachys bambusoides community, G: Rubus corchorifolius community, H: Phramities japonica community, I: Phramites communis community, J: Miscanthus sacchariflorus community, K: Miscanthus sinesis var. purpurascens community, L: Artemisia princeps var. orientalis community, M: Humulus japonicus community, N: Zoysia japonica community, O: Inperata cylindrica var. koenigii community, P: Agropyron tsukushiense var. transiens community, Q: Juncos effusus var. decipiens community, R: Rumex crispus community, S: Persicaria hydropiper community. The vegetation characteristics of riversides was recovered in the surveyed results according to river·stream basin, in other words, 10 communities in the upper river·stream riparian, 15 communities in the middle river·stream riparian, 10 communities in the down river·stream riparian. The Phragmites japonica community in the upper and Phragmites communis community in the down was analyzed by common community of the 6 river·stream riparian, respectively, but none in the middle. The standing profile of vegetation across 6 river·stream was seen stepwise Phragmites japonica community, Salix gracilistyla community, Miscanthus sinensis var. purpurascens community, shrub community by natural waterway in the upper, Salix gracilistyla community, Phragmites communis community, Rumex crispus community, Miscanthus sacchariflorus community, Humulus japonicus community in the middle, Phragmites communis community in the down. The differences of distributional featurs of vegetation emerged from the riparian of the 6 river·stream, but don't from the 6 river·stream.

The medicinal plants in 22 unhabited islands of Jindo-gun, Chonnam provincde were investigated from March 2000 to October 2002. The medicinal plants in 22 uninhabited islands of Jindo-gun were consisted 366 taxa; 95 families, 269 genus, 309 species, 52 varieties, 3 forma, and 2 subspecies. Important medicinal plants on survey area were Lemmaphyllum microphyllum, Dendropanax morbifera, Ficus erecta, Farfugium japonicum, Machilus thunbergii, Juniperus chinensis var. procumbens, Dendrobium moniliforme, Pyrrhosia tricuspis, Cinnamomum japonicum, Pittosporum tobira, Kadsura japonica, and Daphniphyllum macropodum, This result can be used as basic information data for medicinal research and the conservation of uninhabited islands.
