인천 덕적도 식물상과 식생에 관한 연구

Abstract

This study is based on the Deokjeok Island, and identified a total of 334 vascular plants with 85 families, 224 genera, 1 subspecies, 41 varieties and 3 formas. The Pinus densiflora community, which was dominated by the Pinus densiflora, was distributed in the Deokjeok Island. Grassland vegetation, which included the Pueraria thunbergiana, grew around the dock, villages, and farmlands. The Carpinus coreana formed communities on the cliffs along the coast, where ridges of cliffs are connected. Most of the valley vegetation consisted of species of Quercus, which included the Quercus acutissima, Quercus variabilis, Quercus serrata, Quercus mongolica and Quercus aliena. The Pinus densiflora community accounted for the biggest area among all forest communities in the Deokjeok Island, which is 63.46% of the total area (13,243,407.65m2). Next followed the Pinus densiflora-Quercus acutissima community with 4.26%, and the Carpinus coreana community with 3.78%. Therefore as succession proceeds, the area distribution of the Pinus densiflora community is expected to gradually decrease, while the Quercus is expected to increase. Also, it seems that the Quercus acutissima community, the Quercus variabilis community and the Quercus serrata community distributed around the valleys will be replaced by the Acer mono, the Fraxinus rhynchophylla, the Cornus controversa, the Lindera erythrocarpa and the Platycarya strobilacea which are usually distributed around the valleys. In the seashore cliffs, the current Carpinus coreana community is expected to grow further and partially increase its size. The current forest vegetation of Deokjeok Island is mostly the Pinus densiflora community, which appeared at the mid stage of succession. Thus, the overall vegetation in Deokjeok Island seems to be at the early or mid stage of forest succession. If normal succession continues over time, the vegetation of this area is likely to be replaced by the typical forest vegetation, such as the Carpinus coreana and Quercus.
