This study was carried out to develop individual tree growth model of major coniferous species, Pinus densiflora, Pinus koraiensis, and Larix kaempferi, in Korea. Monitoring data for three year was used in this study and the total number of plots was 48 sites for P. densiflora, 135 sites for P. koraiensis, and 135 sites for L. kaempferi. Individual tree growth of DBH, basal area, and height were analyzed using the correlation coefficients and regressions, and each growth models were developed. The eight kinds of measured tree factors from 1st and 2nd inventory at 3 year intervals were used as independent variables for individual tree growth models: DBH, number of competitors, basal area, site index, stand density index, age, relative height, number of trees per ha. In addition, the competition index calculated through the best method was used as an independent variable. According to the dependent variables, the selected independent variables for the best models were different by species and models. The best models by dependent variables were developed in P. koraiensis. Using the individual tree growth models provided in this study, it is considered to be able to develop the more suitable growth models for P. densiflora, P. koraiensis, and L. kaempferi in Korea.
