This study was carried out to estimate the Korean Pine stand structure such as coefficient of variation of mean DRH, number of trees and volume per ha by Weibull distribution for each age class from I to V, based on photo measurement and timber cruising in Kangwon National University Experimental Forests. The results were summarized as follows:
1) Coefficient of variation of mean DBH for each age class from I to V, which was obtained by converting DBH estimated from crown diameter by photo measurement into quadratic mean DBH, was estimated as 28.88%, 24.13%, 23.29%, 20.27%, and 18.79%, respectively. 2) Number of trees per ha of each age class by Weibull distribution was obtained as 2875, 2100, 1875, 800, and 325, respectively. 3) Volume per ha of each age class was estimated as 22.9§©/ha, 66.8§©/ha, 101.3§©/ha, 209.6§©/ha, and 266.8§©/ha, respectively. 4) Therefore, aerial photographs will be helpful to estimate the stand structure effectively.
Key words: aerial photograph, Korean pine stand, stand structure, Weibull distribution
