To develop thinning effect analysis model (TEAM) of Pinus koraiensis stand, individual-tree distance-independent growth model was used. The TEAM was designed to analyze thinning effects associated with such thinning prescriptions as the number, timing, intensity, and method of thinning. To test TEAM application, stand growth effects were compared with seven scenarios according to thinning prescription plan. Finally it was possible to estimate the number of trees, height, volume with DBH class of individual trees, and average diameter growth, height growth, the number of trees and volume growth/ha of stands. The result of sensitivity analysis showed that it was not sure to expect the much more volume at the rotation age by stand density control applying thinning prescription. In the case of thinning, total yield volume has much more 40~75§©/ha, within 5 cm in average diameter growth and within 1 m in average height growth than those of non-thinning over increasing stand age. TEAM, as decision making support system, can be used for selecting the thinning prescription trial and determining one of some thinning prescription plan in different site specific stand environments.
Key words: individual-tree distance-independent model, thinning effect analysis model, thinning prescription, Pinus koraiensis stands
