Abstract

This study is examined river naturality and vegetative composition of river riparian zones to identify their most important sources of variation. Information on plant species cover and on physical characteristics that occur at upper, medium, and low areas was collected for 30 riparian plots located throughout the Youngjeong River in Korea. The riparian areas of river banks are dominated by mixed sediment and the vegetation is composed of herbs, shrub, and trees. The floristic characterization of riparian at this river during 2015 season was identified with a total of 28 families, 72 genera, 75 species, 13 varieties, 23 associations. The vegetations of low water's edge and flood way at upper region were naturally formed various vegetation communities by natural erosion. Forty plant species were identified around the upper region, where the dominant growth form was mostly trees. The flood way vegetation at middle region was both of natural vegetation and artificial vegetation. Land uses in riparian zones river levee at low region were bush or grassland as natural floodplain. The values of cover-abundance at upper, middle, and low region were total 9.26, 7.24, and 7.56, respectively. Grasses and forbs at the Youngjeong River have similar cover-abundance values. Recent, many riparian areas of this river have been lost or degraded for commercial and industrial developments. Thus, monitoring for biological diversity of plant species of this river is necessary for an adaptive management approach and the successful implementation of ecosystem management.

본 연구는 경상남도 사천시 용정천에서 하천의 건강도와 식생 구조를 평가하기 위해 하천의 상, 주, 하류에서 물리적 구조와 30곳의 방형구에서 식물 피도를 조사하였다. 2015년 이 하천의 전체 수변식물상은 28과 72속 75종 13변종이었다. 상류 제방의 식생은 초본, 관목, 교목의 혼합 군락이었다. 상류지역의 하안단구 식생은 자연 침식으로 형성된 식물상이었다. 상류에서는 40종의 식물이 동정되었고 우점 군락은 교목이었다. 중류 지역에서 홍수터는 자연식생과 인공식생이 혼재하였다. 제외지는 초지가 우세하였다. 상, 중, 하류의 피도-풍부도(cover-abundance)는 각각 9.26, 7.24, 7.56이었다. 잎이 좁은 초본과 잎이 넓은 광엽 초본의 피도-풍부도는 유사한 비율을 나타내었다. 최근 이 지역의 하첨 주변은 상업 및 산업 시설이 설치되어 제외지 등에서 많은 하천변 식생이 훼손되었다. 따라서 이 하천의 지속 가능한 유지를 위해서는 생물종 다양성에 대한 모니터링이 필요하다고 사료된다.
