| Özet |
| The aim of this study was to develop single- and double-entry over-bark and under-bark stem volume equations for pure and natural Crimean pine (Pinus nigra J.F. Arnold subsp. pallasiana (Lamb.) Holmboe) stands in Kastamonu Regional Directorate of Forestry. A total of 227 sample trees taken from available sites, densities, and ages were measured for over-bark and under-bark stem volumes. Seven single-entry and twelve double-entry stem volume equations were fitted for over-bark and under-bark stem volume estimations, separately. The fitted equations were ranked according to four goodness-of-fit criteria (coefficient of determination (R2), root mean square error (RMSE), mean absolute error (MAE) and Akaike information criterion (AIC)), and the most successful equations were selected based on relative ranks. Among the tested equations, the most successful single- and double-entry equations for both … |
