Thinning Effect on Biomass Storage of Coniferous Plantations in South Korea

초록

This study was conducted to analyze the effect of thinning intensity on biomass within coniferous plantations (Pinus densiflora, Pinus koraiensis, Larix kaempferi) located in Gangwon and North Gyeongsang provinces, South Korea. According to the analytic results, thinning intensity had a strong influence on the biomass storages of individual trees. As the thinning intensity increased, the biomass of individual trees was found to increase, while the total stand biomass decreased. In control plots, total biomass was the greatest, but the majority of stand biomass came from smaller trees in DBH when compared to the thinned plots. Thinning also influenced the increment of stand biomass. In control plots, stand biomass increased the most but the growth rate was the lowest. This study is expected to be useful with basic information for establishing forest management plans to achieve diverse goals including biomass, sawtimber production, and carbon management.
