Warmth index was calculated with 449 weather points using inverse distance weighted interpolation method. The planting species were selected by correlation analysis between Z. serrata and each species of four or more frequency among the 36 relevé surveyed for this study. The result of this study is summarized as follows： Warmth index of Z. serrata communities was among 74～118°C․month. Results of the correlation analysis between Z. serrata and each species observed that the Z. serrata belongs to the tree layer with warmth index of 80～100 and 100～120°C․month. On the other hand, the species of Carpinus laxiflora, Quercus serrata, Prunus sargentii and Platycarya strobilacea appeared only in the tree layer with warmth index of 80～100°C․month. Z. serrata and Styrax japonica appeared in the subtree layer with the warmth index of 80～100 and 100～120°C․month, while Acer pseudosieboldianum, Lindera erythrocarpa, Acer mono, Quercus serrata, etc. appeared in the subtree layer with the warmth index of 80～100°C․month. Z. serrata, Ligustrum obtusifolium, Lindera obtusiloba, Callicarpa japonica and 공석준․신진호․양금철 78 Zanthoxylum schinifolium all appeared in the shrub layer with the warmth index of 80～100 and 100～ 120°C․month. Lindera erythrocarpa, Orixa japonica, Staphylea bumalda, Akebia quinata and Sorbus alnifolia appeared in the shrub layer with the warmth index of 80～100°C․month and Styrax japonica and Stephanandra incisa appeared in the shrub layer with the warmth index of 100～120°C․month.The numbers of each species planted in a 100m 2 area of the Z. serrata community were suggested as follows：five in tree layer, five in subtree layer and nine in shrub layer. The average area of canopy are suggested to be about 86m 2 for tree layer, 34m 2 for subtree layer and 34m 2 for shrub layer.
