This study was carried out to provide the effect of the site factor on the growth of Japanese larch(Larix kaempferi), which is one of major coniferous species in Korea. In 2013, in order to find out the growth of Japanese larch, permanent plot established in Eastern, Northern and Southern Region of Korea. The permanent plot investigation was repeated every three years, starting with the first investigation when the site was installed, and the fourth investigation is in progress as of 2022. The investigation was performed to measure tree factor (age of tree, DBH(diameter breast height), total height, clear height, number of tree) and site factor(slope, aspect, elevation). In order to provide the effect of the site factor on the growth of the species, one-way ANOVA was performed by site factor. The slope was classified and analyzed into six categories (slope<15°, 15°slope<20°, 20°slope<25°, 25°slope<30°, 30° slope<40°, 40°slope) and the aspect was classified and analyzed into eight categories (north, northeast, east, southeast, south, southwest, west, northwest). The Elevation was classified and analyzed into six categories (Elevation<200m, 200mElevation<400m, 400mElevation<600m, 600mElevation<800, 800mElevation<1000m, 1000mElevation). As a result to one-way variance of analysis, the DBH was not significantly dfferent according to elevation, aspect and slope(p>0.05). Also, the height was not significantly different according to slope and aspect(p>0.05), whereas the height was significantly different according to elevation (p<0.05).
