Based on 29 stems analysis and 140 sample trees of nature Korean pine(Pinus koraiensis Sib.et Zucc.) measured on the Xiaoxing'an Mountain, effects of age ranged from 20 to 300 years on stem form were discussed and a compatible taper and volume ratio system was developed. The merchantable cubic-metre volume ratio table ofvarying log rules was constructed for nature Korean pine in this paper. Results indicated that age classes were regarded as a totality to develop taper equation, The compatible tree profile and volume ratio equation developed in this paper can be used toobtain estimates of individual tree volumes and stem profile or volume of varying merchantability limits.
