다국어 초록 (Multilingual Abstract)

This study is carried out to clarify the changes in the forest vegetational structure as time goes by after the fire.
The results obtained are as follows;
1. The Soil pH decreased, the soil organic matter and water content increased, and the soil structure was hardly changed as time goes by after the fire.
2. By analyzing the soil profile, the soil deepness was shallow in general, and the formation of the organic matter was gradually increased. nced.
3. In relative density, relative cover, relative frequency, Quercus spp., Alnus hirsuta, Lespedeza spp. showed the high value, but that of Lespedeza was decresed as time goes by, and for herbaceous plants Cymbopogon tortilis, Festuca ovina was very high value over all the plot.
4. Importance value of Quercus spp. and Alnus hirsuta was gradually increased, and that of herbaceous plants - Cymbopogon tortilis, Festuca ovina, and Pteridium aquilinum - also was gradually increased, but was decreased in the fifth year.
5. The species diversity showed the low value shortly after the fire, but was increased after the second year, and the eveness index was decreased as time goes by.
