완도지역의 붉가시나무 수간형태와 수간곡선식 = Development of Stem Profile and Taper Equation for Quercus acuta in Wando

다국어 초록 (Multilingual Abstract)

This study was carried out to develop equations for predicting stem taper for Quercus acuta in Wando district. We were used to derive three taper equations from Max and Burkhart, Kozak, and Lee functions.
The models tested for choosing the best-fit equations were Max & Burkhart’s model, Kozak’s model, and Lee’s model. In result, all three models behaved similarly and estimated diameter well at all points along the stem, although Kozak’s model gave slightly better values of fit statistics. In plotting residuals against predicted diameter, Max & Burkhart's and Lee’s model showed underestimation in predicting small diameter. On the other hand, Kozak’s model was quite evenly distributed over the whole range of diameter. Based on the above analysis of three models in predicting stem taper, Kozak’s model was chosen for the best-fit stem taper equations. It was showed the stem volume table by this model, therefore this table was provided user with volume and management information.
