초록
본 연구는 해식애 식생구조의 기초자료로 제공하기 위하여 배열법으로 갯기름나물군락과 동반출현하여 혼생하는 주요 식물의 지형적 분포 및 생육 양상을 분석하였다. 해식애의 갯기름나물군락에서 10% 이상의 출현빈도를 나타내는 혼생식물은 26종이었으며, 출현 빈도가 가장 높은 식물은 해국(55.7%)이었다. 갯기름나물군락의 혼생식물은 내륙육지 방향, 해안선방향, 평탄면, 사면 등의 지형요인별 분포 및 생육 양상을 달러하였다. 그리고 분포 및 생육 양상은 모든 지형요인에서 차이가 없이 고르게 분포하는 전형적 형태, 1개의 지형요인에서 양호한 분포를 나타내는 일방적 형태, 2개 또는 그 이상의 지형요인에서 양호한 분포를 보이는 복합적 형태로 구분되었다. 사철쑥과 땅채송화 등은 전형적 형태, 갯보리와 쑥 등은 일방적 형태의 분포 및 생육 양상을 나타내었고, 해국억새 갯메꽃 갯까치수영 등 16종(전체 혼생식물의 61.5%)의 식물이 복합적 형태로 갯기름나물과 혼생하여 양호한 생육을 보였다.
This study was conducted in order to provide as a basic materials of sea cliff vegetation structure through distribution related with the landform and growth pattern of mixed growth plants by ordination method in the Peucedanum japonicum community of Korea. The mixed growth plants of frequency over 10% growth with Peucedanum japonicum community of sea cliff was investigated as a total 26 species, and the frequency of appearing plants was the highest in the Aster spathulifolius(55.7%). Growing pattern of mixed growth plants was a difference by the landform factors as such the inland side, coastline side, flat and slope. Growing pattern was classified into typicality type, one-sided type and complex type. Growing pattern of the typicality type was good distribution in total landform factors, the one-sided type was good distribution in 1 landform factor and the complex type was good distribution in 2 landform factors. In growing pattern of mixed growth plants with Peucedanum japonicum, Artemisia capillaris and Sedum oryzifolium was typicality type, Elymus dahuricus and Artemisia princeps was one-sided type, and Aster spathulifolius, Miscanthus sinensis, Calystegia soldanella and Lysimachia mauritiana was complex type. In total plants of mixed growth, growing pattern of 16 species of 61.5% was good as complex type.
