A vegetation structure by attitudinal changes from Jeongryongchi to Gogiri section of Baekdudaegan were investigated by sample plots(nine 500$m^2$). Using TWINSPAN and DCA techniques, vegetation structure was analyzed. In the results from the analysis of both techniques, Quercus mongolica is dominant species and attitudinal zonations were divided into 2 groups such as above 900m area and lower one by subspecies in subtree and shrub layers. Similarity index analyses of elevational ranges showed discontinuities between above and lower elevation area. In the analysis of species diversity, there was no significant difference due to altitude.
