The forest of Choksangsansong area was studied to investigate vegetational structure with twenty-five plots(20m$\times$25m). Relative importance values, DBH class distribution, species, diversity indices, DCA ordination and TWINSPAN classification were used for vegetational structure analysis. Quercus mongolica, Carpinus cordata, Quercus serrata and Cornus controversa were appeared to be dominant species in each plot and dominant species in the Choksangsansong area was Quercus mongolica. The forest of Choksangsansong area was classified into four groups and showed seral stage from Quercus mongolica to Carpinus cordata. Vegetational succession in the Choksangsansong area shall be accelerated to moist and shade tolerant species due to cool and humid climatic condition by upper dam construction of the Mujuyangspalchonso (pumping up power station).
