This study was carried out to figure out the competition index of major coniferous species, Pinus densiflora, Pinus koraiensis, and Larix kaempferi, in Korea. As a study on the competition index, the optimal model was selected and the characteristics of the competition index were evaluated according to the stand conditions. The optimal competition index model was selected as the best method of correlation between the competition index and the periodic annual increment of basal area according to various competition selection methods and distance-dependent competition index models. For the competition model, models were used in this study as follows: Lorimer, Martin-EK, Braathe, Heygi, Daniels, modified Daniels. The competition tree selection method was based on the basal area and the angle method using tree height or crown height. As a result of characterizing the calculated competition index according to thinning intensity and tree density by species, the stronger the thinning intensity, the lower the competition index, the lower the competition index. The competitive index of each species through the model suggested in this study was used as an explanatory variable in the development of individual growth model of P. densiflora, P. koraiensis, and L. kaempferi in Korea.
