The annual increasing rate of visitors was 3 percent in Soraksan National Park form 1990 to 1997. Secenty nine percent of total visitors in Soraksan National Park has visited Oysorak district due to convenient access and facilities. Approximately, 6~17 percent of visitors passing through Sorakdong ticket office at Oysorak district has climbed up Taech'ongbong(peak), the others have visited Ulsanbawi, Pisondae and Madungnyong close at hand. Climbers from Osekyaksu to Taech'ongbong(peak)were more in autumn than in summer. Visiting pattern in Soraksan National Park showed differences by districts, seasons and days of the week.

To investigate the structure and the conservation strategy of natural forest at Soch'ongbong-Taech'ongbong Area in Soraksan , 36 plots (20m*20) set up with random sampling method. Three groups - Quercus mongolica- Abies holophylla community, Acer mandshuricum- Abies nebhrolepis community, Abies holophylla-Ulmus laciniata-were classified by cluster analysis. High positive correlations were proved between Ulmus laciniata and Carpinus cordata; Tripterygium regelii and Syringa reticulata var. mandshurica ; Tripterygium regelii and Rhodo- dendron brachycarpum ; Carpinus cordata and Rhododenron mucronulatm; Wergela subsessilis and Rhododenron nucronulatum and High negative correlations were proved between Rhododen- dron schippenbachii and Euonymus macroptera; Betula ermani and Acer pseudo-sieboldianum, Tilia amurensis, Magnolia sieboldii, Betula costata ; Pinus pumila and Pinus koraiensis. Species diversity(H') of investigated area was calculated 0.8393~1.3431.

The forests of Osaek-Taech'ongbong-Shinhungsa district in Soraksan National Park was studied to investigate forest structure of tree strata in relation to aspect and altitude of the slope. Excepting the main ridge area which has tyoical environmental condition, tree siwe in canopy of the wouthern slope was smaller, density in canopy of the southern slope was higher and species diversity in tree stratum of the southern slope was lower as compared those of the northern slope of same elevation belts. Elevation trend was found for forest structure of the southern slope where geographical features were similar among elevation belts. With incleasing elevation of the southern slope, basal area of canopy and understory increased. With increasing elevation of the southern slope, importance values of Quercus mongolica, Styrax obassia, and Lindera obtusiloba decreased while those of Pinus koraiensis, Betula ercani, Acer tschonoskii var. rubripes and Rhododendron schlippenbachii increased. According to cluster and ordination analysis, the studied forests was classifide into Quercus mongolica community at the low, middle and high elevation belts of the southern slope and the low and middle elevation belts of the northern slope, Betula ermani community at the elevation belt of the northern slope, and Abies koreana community at the top area.

To investigate the structure and the conservation strategy of natural forest at Taech'ongbong-Hangyeryong Area in Soraksan. 45 plots(20m*20m) set up with random sampling method were surveted. Four groups - Quercus mongolica - Acer pseudosieboldianum community, Avies nephrolepis - Tilia amurensis - Quercus mongolica community, Abies nephrolepis - Taxus cuspidata community, Abies nephrolepis - Qurecusmongolica community - were classified by cluster analysis. High positive correlations were proved between Abies nephrolepis and Betula ermanii; Abies nephrolepis and Pinus pumila; Aies nephrolepis and Rhododendron mucronulatum var. ciliatum; Betula ermanii and Pinus pumila; Betula ermanii and Rhododendron mucronulatum var. ciliatum; Pinus pumila and Rhododendron mucronulatm var. ciliatum; Quercus mongolica and Rhododendron schlippenbachii; Quercus mongolica and Qeigela subsessilis; Euonymus macroptera and Syringa reticulata; Euonymus macroptera and Viburnum wrightii; Acer ukurunduense and Euonymus oxyphyllus, and high nagative correlations were proved between Betula ermanii and Acer pseudosieboldianum; Quercus mongolica and Tripterygium regelii; Rhododendron schlippenbachii and Tripterygium regelii; Carpinus cordata and Acer pseudosieboldianum. Species diversity(H') of investigated area was calculated 2.1352~2.8016.

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.
