Site Index and Height Growth Curve of Larix leptolepis and Pinus koraiensis <Jour. Kor. For. Soc. 68:11-17 1985> Senior author Hyun-Seo Cho
Height growth curve to be required for estimating site index was formulated with 10 models based on the average tree height and tree age. Among them, the model of H= K-abA was evaluated to be best fit for estimating average tree height (H) with tree age (A). Equations, H= 28.364-25.125(0.886)A and H= 26.331-25.125(0.886)A, were situated from the model for estimating average tree height of Larix leptolepis and Pinus koraiensis, respeftively (in this case the tree age was categorized into 0 for 5-year-old tree, 1 for 10-year-old tree and 2 for 15-year-old tree etc.). Result of comparing the site indices calculated by the Bryant method, it was proved that the site index of Larix leptolepis was estimated higher than that of Pinus koraiensis within the limits of site index class 6 to 18. On the contrary the site index of Pinus koraiensis turned out to surpass that Larix leptolepis at the site index class 20 or over.
Key words: Larix leptolepis, Pinus koraiensis, height growth curve, site index
