A survey was conducted on the vegetation of southern slope of Daecheong-bong, Mt. Seolag, Located at the northern part of Taebaek mountain chain in the Central Korea. The altitudinal zonation of the vegetation was analyzed by distribution pattern of dominant species along thermal gradient, In additiion to these procedure th plant sociological studies by Braun-Blanquet(1964) were carried out. It was recognized that the vegetation is consist of 16 associations including Quercus mongolica-Lindera obtusiloba. association and the forest zone is classified into southern, central and northern part of cool temperate forest and subarctic forest.

Altitudinal changes in the vegetation of Sunginbong(984m) in UIlungdo (Island) were investigated by sample plots(forty l00$\m^2$) along elevation and analyzed by TWINSPAN and DCA techniques. In the results from the analysis of both techniques, altitudinal zonations were divided into 3 groups such as lower 300m area, 400~700m area, and above 800m area. DCA and similarity index analyses of elevational ranges showed discontinuities between lower and middle elevation areas. But there was a vegetation continuum between middle and high elevation areas. In the analysis of species diversity, there was no significant difference due to altitude except for maximum species diversity which was decreased with altitude. The mean tree density of canopy and understory layers in the middle elevation area showed the highest value, and the highest basal area was recorded at the lower elevation area.
