Through the vegetation survey of Geumcheon Valley on the south-facing slope and the other side of the valley, Jedanggol on the north-facing slope in Taebaeksan Provincial Park, the characteristics of vegetation structure and change by slope and altitude were examined. From Geumcheon Valley(850m) via the ridge(1,380m) to Jedanggol(950m), thirty plots at intervals of 50m altitude were selected for investigation. According to the results of the analysis, Acer pictum subsp. mono, Fraxinus rhynchophylla, Betula davurica and Lindera obtusiloba were observed only in the south-facing slope, while Sorbus commixta, Prunus padus, Prunus maackii and Acer komarovii were observed only in the north-facing slope. However, Quercus mongolica, Betula costata, Cornus controversa, Tilia amurensis, Acer pseudosieboldianum and Magnolia sieboldii were found to be distributed over both the slopes. The analysis of ordination found that the vegetation was distributed discontinuously by slope. Especially, the vegetation of the north-facing slope appeared to be affected by the direction that the slope faces. Quercus mongolica community, which is the dominant species at an altitude of over 1,200m, was determined to be affected by elevation factor. The maximum age of the major trees was as follows: Betula costata and Quercus mongolica were estimated to be 53-year-old and 113-year-old respectively.
