  • To investigate the vegetation structure of mountain ridge from Pijae to Doraegijae in Baekdudaegan, forty-three sites(size 500$m^2$) were set up and surveyed By using TWINSPAN classification. the plant community was divided into five groups, those are mixed forest on sub-alpine zone. Quercus mongolica - Acer pseudo-sieboldianum community, Q. mongolica-Pinus densiflora community, and Larix leptolepis forest. Quercus mongolica was found as a major woody plant species in the ridge area. And partly the subalpine zone in low elevation was occupied by deciduous tree species and mixed a few conifer such as Abies nephrolepis and Taxus cuspidata etc.. Species diversity index(Area 1,000$m^2$) in the showed calculated 2.0149~3.0139 and it was similar to those of the ridge area of the national parks in Beakdudaegan.

  • For the zoning of natural ecosystem, Vegetation Index is calculated from the vegetation data surveyed on Baekdudaegan (Pijae-Doraegijae). Five factors -biodiversity, conservation value of the stand, environmental quality, longevity of the stand, site productivity- are considered in the calculation of Vegetation Index. Vegetation Index might be a useful zoning tool for management of Baekdudaegan. For Vegetation Index I, 59 sample plots 52.2% of total 113 sample plots are belong to core area, 34 sample plots 30.l% and 20 sample plots 17.7% are belong to buffer zone and transition area, respectively. For Vegetation Index II, 49 sample plots 43.4% of total 113 sample plots are belong to core area, 38 sample plots 33.6% and 26 sample plots 23.0% are belong to buffer zone and transition area, respectively.
