동복천 일대 수계의 식물 사회학적 연구

Abstract

Classification and description of the riverside vegetation around Dongbok stream, Korea was studied. The vegetation was divided into thirteen associations. Reflecting various human impacts in the past, the associations and communities of the Artemisietea principis were most plentiful there. The vegetation units obtained in the present study were as follow: Forest vegetation: Pinus densiflora community, Quercus acutissima community, Pinus rigida community, Shrub vegetation: Salix gracilistyla community, Grassland vegetation: Polygonetum thunbergii, Phragmitetum japonicae, Phragmites australis community, Artemisia princips community, Humulus japonicus community, Miscanthus sinensis community, Rumex crispus community, Setaria viridis community, Erigeron canadensis community. It was inferred that the endemic vegetation units in the riverside vegetation of Korea were very rare, because most of the vegetation units obtained in the present study were common with those of Japan. On the other hand, the associations and communities of classes characterizing the riverside vegetation increased with a decreased of human impacts from the downstream to the upstream in Dongbok stream, while the number of the naturalized plants was the reverse.
