Community Classification and Vegetation Pattern of Quercus mongolica Forest in Mt. Myongji

명지산 신갈나무림의 군락분류와 식생패턴

The Quercus mongolica forest vegetation of Mt. Myongji was classified into two communities including four subunit communities and one typical subunit community by the Z-M method as follows: Acer pseudo-sieboldianum-Quercus mongolica community group Quercus mongolica - Isodon excisus community Quercus mongolica - Styrax obassia community Quercus mongolica - Lespedeza bicolor subunit coummunity Quercus mongolica - Aconitum longecassidatum subunit community Quercus mongolica - Rhododendrom schlippenbachii subunit community Quercus mongolica - Cornus controversa subunit community Quercus mongolica - Styrax obassia typical subunit community Acer pseudo-sieboldianum - Quercus mongolica community group was distributed over the upper region of the altitude 400m, and the differential species in the community were Carex siderosticata, Sephanandra incisa, Tripterygium regelii, and Fraxinus rhynchophylla. The vegetation patterns for the slope and azimuth showed that the highest importance value for Quercus mongolica forest was observed on the broad subxeric area, and for Carpinus cordata and Acer pseudo-sieboldianum on the wet site, for Acer mono, Styrax obassia, Fraxinus rhynchophylla and Symplocos chinensis for. pilosa on the xeric site. The best habitat condition for Quercus mongolica was found at a subxeric site at the altitude of 700-900m on southern slope and that for Acer pseudo-sieboldianum at the 700-1100m on northern slope.
