Phytosocological Study on Montance Forest Vegetation at periphery of Seoul, Korea

서울근교 산지의 삼림식생에 대한 식물사회학적 연구

The forest vegetation occurring mainly at the mountain areas in periphery of Seoul were inversigated phyeosociologically. The granitic rocky outcrops are typical physiognomy on the study areas. The greater part of forests was the secondary vegetation to be disturbed by hyman impacts, because of being situated near the metropolis with a highly dense population. Four community types were largely differentiated by species composition. The representitive ones were the Quercus monogolica community and Pinus densiflora-Juniperus schinensis community, which are predominantly gorwing at the slopes above about 100m in altituse and the rocky ridges, respectively. The Betula chinensis-Potentilla dickinsii community at several single-peaks of windswept and the Zelkova serrata-Prunus padus community at stony valley are sporadically growing in a small area.
