Vegetation Structure and Management Planning of Guryong Valley in Chiak National Park This study was conducted to draw plant landscape elements in the ancient literature, investigate current vegetation and plant community structure, understand vegetation structure, and suggest reasonal conservation management methods. Main researches were ancient literature analysis and plant structure features. Ancient literature and ancient map were analyzed, plant landscape elements were categorized and plant landscape was deduced at those times. Current plant, community classification, the number of species and its population, species diversity index, and similarity index were searched and analyzed to comprehend nature of plant landscape. As a result of analyzing ancient literature, geomorphological landscapes in Guyong valley were canyon landscape and valley surrounded in Mt. Chiak. Plant landscape factors were as followed. Rhododendron schlippenbachii and Azalea spread around valley and Guyong temple. Especially, entrance zones of Guyong valley were written as covered with Pinus densiflora. Hence, it was estimated that entry of Guyong valley was covered with Pinus densiflora community landscape. There were Pinus densiflora and Abies holophylla community landscape around uyong temple, and the dominant plant landscape of Guyong valley was Deciduous broadleaved. As for current vegetation result, 87.2% of plant was natural plant : Pinus densiflora forest, Pinus densiflora - Deciduous broadleaved forest, Pinus densiflora-Quercus serrata forest, Quercus serrata forest, Salix-Acer ginnala forest, and Deciduous broadleaved forest. 5% of plant was artificial plant. : White pine forest, Abies holophylla forest, and Abies holophylla forest-Pinus densiflora forest. 7.8% was others like natural streams, shelters, camp sites, and religion facilities. As a result of classification by TWINSPAN for community classification, five communities (Deciduous broadleaved community, Pinus densiflora community, Pinus densiflora - Abies holophylla community, Abies holophylla community, and Pinus koraiensis community) were classified. In community Ⅰ(Deciduous broadleaved community), dominant species was Quercus serrata but it was judged to compete with Carpinus laxiflora. Community Ⅱ (Pinus densifora community) was highly dominant in tree layer, but it rarely appeared in sub-tree layer and shrub layer. So, it was expected to be turned into Quercus community. In community Ⅲ (Pinus densiflora - Abies holophylla), Pinus densiflora and Abies holophylla were dominant, but it would be mixed species forest during transient procedure. In community Ⅳ, it was expected for Abies holophylla community to be kept. In community Ⅴ, Pinus koraiensis was dominant and it would also be expected for Pinus koraiensis community landscape to be kept. According to species diversity index by Shannon, the index was 1.1500~1.4319. It meaned all communities had stable plant structure. The index of similarity by communities was 7.09~65.33%. Each community had 32.2 species and 547.2 trees / 100㎡. This study was conducted to suggest plant management plan for conservation of crucial resources and historical and cultural landscape. For plant management in Guyog valley, Deciduous broadleaved community was selected as nature adaptive succession inducement management area (293,238㎡) maintained actual vegetation to preserve natural landscape. Pinus densiflora - Pinus abies community, Pinus abies community were chosen as passive density management area (19,397㎡) for maintaining forest landscape and passive management method by eliminating broadleaved trees in understory was suggested. To maintain landscape and conserve crucial resources, Pinus densiflora community was classified as concentrated conservation management area for fostering next generation forest through conserving seedlings like eliminating broadleaved trees and Sasa borealis, main covering plant. These conservation and management areas occupied total 105,472㎡ within Guyong valley. Among those, some centralized management areas were chosen. They were Pinus densiflora lower layer forest management area (84,029㎡) caused by succession and Pinus densiflora seedling conservation management area (21,443㎡) caused by covering Sasa borealis. Pinus densiflora lower layer flora management area needed to be managed by eliminating Quercus serrata and Quercus mongolica in understory. They were 4∼6 trees / 100㎡ and their average diameter was 7.1 ㎝. In Pinus densiflora seedling conservation management area, Sasa borealis covering ratio and the number of Pinus densiflora seedling should remain constant level, monitoring of growing status should be continuous, and eliminating and managing Sasa borealis should immediately be done. Likewise, traditional Pinus densiflora forest is a historically cultural heritage to preserve with sustainable interest and survey. Efficient management method through systematic monitoring system should be made.
