To investigate the forest structure in Ijontong Cholto area, twenty four plots were set up (each l0$\times$10m ) and surveyed. According to the analysis of ordination by DCA, community divided into 5 groups. The divided groups are Quercus serrata -Q. valiabilis community(I), Q. serrata - Pinus densiflora community(II), Q. mongolica - Lindera obtusiloba community(III), Carpinus laxiflora - Acer pseudo-sieboldianum community(IV) and Acer mono community(V). So the successional trends seems to be from P. densiflora through Q. serrata, Q. valiabilis, Q. mongolica to C. laxiflora, C. cordata, A. mono in canopy layer. And in the subtree and shrub layer, it was expected that from Rhododendron mucronulatum, Rh. schlippenbachii to A. pseudo-sieboldianum, L. obtusiloba. But some sites were likely to become Q. mongolica edaphic climax.
