Estimating the Uncertainty and Validation of Basic Wood Density for Pinus densiflora in Korea

摘要

According to the IPCC guideline (2006), uncertainty assessment is very important in terms of the greenhouse gas inventory. Therefore, the purpose of this study is to estimate the basic wood density (BWD) and its uncertainty for Pinus densiflora in Korea. In this study, Pinus densiflora forests were divided into two eco-types which were Gangwon and Jungbu regions. A total of 33 representative sampling plots was selected to collect sample trees after considering the tree ages and DBH distributions. TheBWD showed statistically no difference between age classes based on IPCC's classification. While, it showed statistically difference(p-value=0.0017) between eco-types. The BWD and uncertainty was 0.396(g/cm~2) and 12.9(%) for Pinus densiflora in Gangwon, while it was 0.470(g/cm~2) and 3.8(%) for Pinus densiflora in Jungbu. The values of the BWD uncertainty for Pinus densiflora were more precised than the values given by the IPCC guideline.
