Estimation of Site Index and Stem Volume Equations for Larix leptolepis Stand in Jinan, Chonbuk

摘要

The objectives of this study were to derive site index and stem volume prediction equation based on stem analysis data for Larix leptolepis in Jinan region. The function for site index was developed by algebraic difference equation method. Polymorphicsite index family curves with base age of 40 were presented based on the Schumacher height equation. The best stem volume prediction equation was suggested as V=0.00260+ 0.00000399D~2H. The simultaneous F-test using this equation showed that the estimated tree stem volumes were not significantly different (α=0.05 level) from the observed stem volumes for model evaluation. Therefore, site index and volume prediction equations prepared in this study could provide an indication of site quality and basicinformation for making of yield table, and could be used for rational forest management of Larix leptolepis stands grown in Jinan region.
