다국어 초록 (Multilingual Abstract)

Eight major trails of Soraksan National Park were selected to investigate the use impacts on environmental edterioration of trail according to the different amount of use. The entire width, bare width, maximum depth and slope of trail as the trail condition surveyed at the total of 188 points were significantly greater on the more heavily-used trail. Major deterioration types of trail were root-exposure, widening, rock-exposure, divergence in order of frequency. And trail conditions of edteriorated points were significantly different from those of non-deteriorated points. The damaged area more severe than Class 4 on trail reached about 10,864m$^{2}$ in total, and especially about 4,560m$^{2}$ in the section between Huiunkak Shelter-Munomigogae trail. The dominant trees of trail edge vegetation were be Quercus mongolica in upper layer, but in lower lauer Carpinus laxiflora, Lespedeza maximowiczii for valley and Carpinus laxiflora, Ghododendron mucronulatum var. cilatum, Tripterygium regelii for ridge.. Especially coverage and number of individuals was highest on Munomighgae-Taech'ongbong trail of the largest use of amount, and each trail was dissimilar in species composition of lower layer of edge vegetation.
