The aim of this study was to characterize the forest vegetation structure and site of Quercus mongolica forest for ecological forest management and ecological niche. The results are as follows : the dominant species in Quercus mongolica forest were Quercus mongolica, Acer pseudosieboldinum, Rhododendron schlippenbachii, Acer mono, Tilia amurensis, and Fraxinus rhynchophylla. DBH analysis showed thar Quercus mongolica seems to remain as a dominant species for the present because they had normal distribution density, that is, low density of big and small individuality, highdensity of middle individuality. With the classification of TWLNSPAN, Quercus mongolica community was classified four groups, such as Quercus mongolica-Sorbus alnifolia, Quercus mongolica-Tilia amurensis, Quercus mongolica-Fraxinus sieboldiana, and Quercus mongolica-Styrax obassia communities. The results of the correlation analysis of Quercus mongolica major communities and environment factors are as follows; Quercus momgolica-Tilia amurensis community was found in gentle sloped area that has high percentage Ca, Mg CEC and low percentage available phosphorus. Quercus mongolica-Sorbus alnifolia community was found in middle sloped area that has middle percentage Ca, Mg, CEC and available phosphours. Quercus mongolica-Fraxinus sieboldiana community was found in steep sloped area that has low percentage Ca, Mg, CEC and high percentage available phosphorus. Quercus mongolica-Styrax obassia community was found in steep sloped area that has middle percentage Ca, available phosphorus and low percentage Mg, CEC.
