一般講演（ポスター発表） P3-295A (Poster presentation)
This study was carried out to evaluate belowground carbon storage by stand age sequences of red pine (Pinus densiflora) and cork oak (Quercus variabilis) stands in southern Korea. Eighteen 20 m x 20 m plots with nine red pine and nine cork oak natural stands were established with various stand ages. Forest floor and soil carbon storage were measured. Carbon storage of forest floor in both stands was not different between young stands (5.54-5.88 Mg C/ha) and old stands (5.36-5.64 Mg C/ha). However, carbon storage at 50 cm soil depth was generally higher in old stands than in young stands of cork oak stands, while the carbon storage in red pine did not show any patterns. The carbon storage at 50 cm soil depth was higher in red pine (92.59 Mg C/ha) than in cork oak (64.35 Mg C/ha) stands. The results indicate that belowground carbon storage in a regional scale is dependent on spatial variation rather than stand age sequence of red pine and cork oak stands in southern Korea.
